// derived from file names, and jQuery is normally delivered in a lowercase
// file name. Do this after creating the global so that if an AMD module wants
// to call noConflict to hide this version of jQuery, it will work.

// Note that for maximum portability, libraries that are not jQuery should
// declare themselves as anonymous modules, and avoid setting a global if an
// AMD loader is present. jQuery is a special case. For more information, see

 * Helper function to fit a radial linear scale with point labels

	// Right, this is really confusing and there is a lot of maths going on here
	// The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
	//
	// Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
	//
	// Solution:
	//
	// We assume the radius of the polygon is half the size of the canvas at first
	// at each index we check if the text overlaps.
	//
	// Where it does, we store that angle and that index.
	//
	// After finding the largest index and angle we calculate how much we need to remove
	// from the shape radius to move the point inwards by that x.
	//
	// We average the left and right distances to get the maximum shape radius that can fit in the box
	// along with labels.
	//
	// Once we have that, we can find the centre point for the chart, by taking the x text protrusion
	// on each side, removing that from the size, halving it and adding the left x protrusion width.
	//
	// This will mean we have a shape fitted to the canvas, as large as it can be with the labels
	// and position it in the most space efficient manner
	//

	// Right, this is really confusing and there is a lot of maths going on here
	// The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
	//
	// Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
	//
	// Solution:
	//
	// We assume the radius of the polygon is half the size of the canvas at first
	// at each index we check if the text overlaps.
	//
	// Where it does, we store that angle and that index.
	//
	// After finding the largest index and angle we calculate how much we need to remove
	// from the shape radius to move the point inwards by that x.
	//
	// We average the left and right distances to get the maximum shape radius that can fit in the box
	// along with labels.
	//
	// Once we have that, we can find the centre point for the chart, by taking the x text protrusion
	// on each side, removing that from the size, halving it and adding the left x protrusion width.
	//
	// This will mean we have a shape fitted to the canvas, as large as it can be with the labels
	// and position it in the most space efficient manner
	//

		 * rows are found, the data returned is the original data array/object that was used to
		 * create the row (or a generated array if from a DOM source).

		 * This method is often useful in-combination with $ where both functions are given the

		 *  @param {string} [oOpts.order=current] Order of the data in the processed array.
		 *    Can be either 'current', whereby the current sorting of the table is used, or
		 *    'original' whereby the original order the data was read into the table is used.
		 *  @param {string} [oOpts.page=all] Limit the selection to the currently displayed page
		 *    ("current") or not ("all"). If 'current' is given, then order is assumed to be
		 *    'current' and filter is 'applied', regardless of what they might be given as.
		 *  @returns {array} Data for the matched elements. If any elements, as a result of the

	/**
	 * DataTables API class - used to control and interface with  one or more
	 * DataTables enhanced tables.
	 *
	 * The API class is heavily based on jQuery, presenting a chainable interface
	 * that you can use to interact with tables. Each instance of the API class has
	 * a "context" - i.e. the tables that it will operate on. This could be a single
	 * table, all tables on a page or a sub-set thereof.
	 *
	 * Additionally the API is designed to allow you to easily work with the data in
	 * the tables, retrieving and manipulating it as required. This is done by
	 * presenting the API class as an array like interface. The contents of the
	 * array depend upon the actions requested by each method (for example
	 * `rows().nodes()` will return an array of nodes, while `rows().data()` will
	 * return an array of objects or arrays depending upon your table's
	 * configuration). The API object has a number of array like methods (`push`,
	 * `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
	 * `unique` etc) to assist your working with the data held in a table.
	 *
	 * Most methods (those which return an Api instance) are chainable, which means
	 * the return from a method call also has all of the methods available that the
	 * top level object had. For example, these two calls are equivalent:
	 *
	 *     // Not chained
	 *     api.row.add( {...} );
	 *     api.draw();
	 *
	 *     // Chained
	 *     api.row.add( {...} ).draw();
	 *
	 * @class DataTable.Api
	 * @param {array|object|string|jQuery} context DataTable identifier. This is
	 *   used to define which DataTables enhanced tables this API will operate on.
	 *   Can be one of:
	 *
	 *   * `string` - jQuery selector. Any DataTables' matching the given selector
	 *     with be found and used.
	 *   * `node` - `TABLE` node which has already been formed into a DataTable.
	 *   * `jQuery` - A jQuery object of `TABLE` nodes.
	 *   * `object` - DataTables settings object
	 * @param {array} [data] Data to initialise the Api instance with.
	 *
	 * @example
	 *   // Direct initialisation during DataTables construction
	 *   var api = $('#example').DataTable();
	 *
	 * @example
	 *   // Initialisation using a DataTables jQuery object
	 *   var api = $('#example').dataTable().api();
	 *
	 * @example
	 *   // Initialisation as a constructor
	 *   var api = new $.fn.DataTable.Api( 'table.dataTable' );

		/**
		 * DataTables can be instructed to load data to display in the table from a
		 * Ajax source. This option defines how that Ajax call is made and where to.
		 *
		 * The `ajax` property has three different modes of operation, depending on
		 * how it is defined. These are:
		 *
		 * * `string` - Set the URL from where the data should be loaded from.
		 * * `object` - Define properties for `jQuery.ajax`.
		 * * `function` - Custom data get function
		 *
		 * `string`
		 * --------
		 *
		 * As a string, the `ajax` property simply defines the URL from which
		 * DataTables will load data.
		 *
		 * `object`
		 * --------
		 *
		 * As an object, the parameters in the object are passed to
		 * [jQuery.ajax](http://api.jquery.com/jQuery.ajax/) allowing fine control
		 * of the Ajax request. DataTables has a number of default parameters which
		 * you can override using this option. Please refer to the jQuery
		 * documentation for a full description of the options available, although
		 * the following parameters provide additional options in DataTables or
		 * require special consideration:
		 *
		 * * `data` - As with jQuery, `data` can be provided as an object, but it
		 *   can also be used as a function to manipulate the data DataTables sends
		 *   to the server. The function takes a single parameter, an object of
		 *   parameters with the values that DataTables has readied for sending. An
		 *   object may be returned which will be merged into the DataTables
		 *   defaults, or you can add the items to the object that was passed in and
		 *   not return anything from the function. This supersedes `fnServerParams`
		 *   from DataTables 1.9-.
		 *
		 * * `dataSrc` - By default DataTables will look for the property `data` (or
		 *   `aaData` for compatibility with DataTables 1.9-) when obtaining data
		 *   from an Ajax source or for server-side processing - this parameter
		 *   allows that property to be changed. You can use Javascript dotted
		 *   object notation to get a data source for multiple levels of nesting, or
		 *   it my be used as a function. As a function it takes a single parameter,
		 *   the JSON returned from the server, which can be manipulated as
		 *   required, with the returned value being that used by DataTables as the
		 *   data source for the table. This supersedes `sAjaxDataProp` from
		 *   DataTables 1.9-.
		 *
		 * * `success` - Should not be overridden it is used internally in
		 *   DataTables. To manipulate / transform the data returned by the server
		 *   use `ajax.dataSrc`, or use `ajax` as a function (see below).
		 *
		 * `function`
		 * ----------
		 *
		 * As a function, making the Ajax call is left up to yourself allowing
		 * complete control of the Ajax request. Indeed, if desired, a method other
		 * than Ajax could be used to obtain the required data, such as Web storage
		 * or an AIR database.
		 *
		 * The function is given four parameters and no return is required. The
		 * parameters are:
		 *
		 * 1. _object_ - Data to send to the server
		 * 2. _function_ - Callback function that must be executed when the required
		 *    data has been obtained. That data should be passed into the callback
		 *    as the only parameter
		 * 3. _object_ - DataTables settings object for the table
		 *
		 * Note that this supersedes `fnServerData` from DataTables 1.9-.

		 *  @name DataTable.defaults.column.dataProp
		 */


		/**
		 * This property can be used to read data from any data source property,
		 * including deeply nested objects / properties. `data` can be given in a
		 * number of different ways which effect its behaviour:
		 *
		 * * `integer` - treated as an array index for the data source. This is the
		 *   default that DataTables uses (incrementally increased for each column).
		 * * `string` - read an object property from the data source. There are
		 *   three 'special' options that can be used in the string to alter how
		 *   DataTables reads the data from the source object:
		 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
		 *      Javascript to read from nested objects, so to can the options
		 *      specified in `data`. For example: `browser.version` or
		 *      `browser.name`. If your object parameter name contains a period, use
		 *      `\\` to escape it - i.e. `first\\.name`.
		 *    * `[]` - Array notation. DataTables can automatically combine data
		 *      from and array source, joining the data with the characters provided
		 *      between the two brackets. For example: `name[, ]` would provide a
		 *      comma-space separated list from the source array. If no characters
		 *      are provided between the brackets, the original array source is
		 *      returned.
		 *    * `()` - Function notation. Adding `()` to the end of a parameter will
		 *      execute a function of the name given. For example: `browser()` for a
		 *      simple function on the data source, `browser.version()` for a
		 *      function in a nested property or even `browser().version` to get an
		 *      object property if the function called returns an object. Note that
		 *      function notation is recommended for use in `render` rather than
		 *      `data` as it is much simpler to use as a renderer.
		 * * `null` - use the original data source for the row rather than plucking
		 *   data directly from it. This action has effects on two other
		 *   initialisation options:
		 *    * `defaultContent` - When null is given as the `data` option and
		 *      `defaultContent` is specified for the column, the value defined by
		 *      `defaultContent` will be used for the cell.
		 *    * `render` - When null is used for the `data` option and the `render`
		 *      option is specified for the column, the whole data source for the
		 *      row is used for the renderer.
		 * * `function` - the function given will be executed whenever DataTables
		 *   needs to set or get the data for a cell in the column. The function
		 *   takes three parameters:
		 *    * Parameters:
		 *      * `{array|object}` The data source for the row
		 *      * `{string}` The type call data requested - this will be 'set' when
		 *        setting data or 'filter', 'display', 'type', 'sort' or undefined
		 *        when gathering data. Note that when `undefined` is given for the
		 *        type DataTables expects to get the raw data for the object back<
		 *      * `{*}` Data to set when the second parameter is 'set'.
		 *    * Return:
		 *      * The return value from the function is not required when 'set' is
		 *        the type of call, but otherwise the return is what will be used
		 *        for the data requested.
		 *
		 * Note that `data` is a getter and setter option. If you just require
		 * formatting of data for output, you will likely want to use `render` which
		 * is simply a getter and thus simpler to use.
		 *
		 * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The
		 * name change reflects the flexibility of this property and is consistent
		 * with the naming of mRender. If 'mDataProp' is given, then it will still
		 * be used by DataTables, as it automatically maps the old name to the new
		 * if required.

		/**
		 * This property is the rendering partner to `data` and it is suggested that
		 * when you want to manipulate data for display (including filtering,
		 * sorting etc) without altering the underlying data for the table, use this
		 * property. `render` can be considered to be the the read only companion to
		 * `data` which is read / write (then as such more complex). Like `data`
		 * this option can be given in a number of different ways to effect its
		 * behaviour:
		 *
		 * * `integer` - treated as an array index for the data source. This is the
		 *   default that DataTables uses (incrementally increased for each column).
		 * * `string` - read an object property from the data source. There are
		 *   three 'special' options that can be used in the string to alter how
		 *   DataTables reads the data from the source object:
		 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
		 *      Javascript to read from nested objects, so to can the options
		 *      specified in `data`. For example: `browser.version` or
		 *      `browser.name`. If your object parameter name contains a period, use
		 *      `\\` to escape it - i.e. `first\\.name`.
		 *    * `[]` - Array notation. DataTables can automatically combine data
		 *      from and array source, joining the data with the characters provided
		 *      between the two brackets. For example: `name[, ]` would provide a
		 *      comma-space separated list from the source array. If no characters
		 *      are provided between the brackets, the original array source is
		 *      returned.
		 *    * `()` - Function notation. Adding `()` to the end of a parameter will
		 *      execute a function of the name given. For example: `browser()` for a
		 *      simple function on the data source, `browser.version()` for a
		 *      function in a nested property or even `browser().version` to get an
		 *      object property if the function called returns an object.
		 * * `object` - use different data for the different data types requested by
		 *   DataTables ('filter', 'display', 'type' or 'sort'). The property names
		 *   of the object is the data type the property refers to and the value can
		 *   defined using an integer, string or function using the same rules as
		 *   `render` normally does. Note that an `_` option _must_ be specified.
		 *   This is the default value to use if you haven't specified a value for
		 *   the data type requested by DataTables.
		 * * `function` - the function given will be executed whenever DataTables
		 *   needs to set or get the data for a cell in the column. The function
		 *   takes three parameters:
		 *    * Parameters:
		 *      * {array|object} The data source for the row (based on `data`)
		 *      * {string} The type call data requested - this will be 'filter',
		 *        'display', 'type' or 'sort'.
		 *      * {array|object} The full data source for the row (not based on
		 *        `data`)
		 *    * Return:
		 *      * The return value from the function is what will be used for the
		 *        data requested.
		 *
		 *  @type string|int|function|object|null
		 *  @default null Use the data source value.

		 * Ordering plug-ins - custom data source

		 * The extension options for ordering of data available here is complimentary

		 * allows much greater control over the the data that is being used to
		 * order a column, but is necessarily therefore more complex.
		 *
		 * This type of ordering is useful if you want to do ordering based on data
		 * live from the DOM (for example the contents of an 'input' element) rather
		 * than just the static string that DataTables knows of.
		 *
		 * The way these plug-ins work is that you create an array of the values you
		 * wish to be ordering for the column in question and then return that
		 * array. The data in the array much be in the index order of the rows in
		 * the table (not the currently ordering order!). Which order data gathering
		 * function is run here depends on the `dt-init columns.orderDataType`
		 * parameter that is used for the column (if any).
		 *
		 * The functions defined take two parameters:
		 *
		 * 1. `{object}` DataTables settings object: see
		 *    {@link DataTable.models.oSettings}
		 * 2. `{int}` Target column index
		 *
		 * Each function is expected to return an array:
		 *
		 * * `{array}` Data for the column to be ordering upon
		 *
		 *  @type array
		 *
		 *  @example
		 *    // Ordering using `input` node values
		 *    $.fn.dataTable.ext.order['dom-text'] = function  ( settings, col )
		 *    {
		 *      return this.api().column( col, {order:'index'} ).nodes().map( function ( td, i ) {

			 * functions this object with a parameter name which matches the sType
			 * for that target column. This is the corollary of <i>afnSortData</i>

			 *
			 * Each ordering option can be described by three properties added to

			 * * `{type}-desc` - Descending order function
			 *
			 * All three can be used together, only `{type}-pre` or only

			 * that only `{type}-pre` is used, as this provides the optimal
			 * implementation in terms of speed, although the others are provided
			 * for compatibility with existing Javascript sort functions.
			 *
			 * `{type}-pre`: Functions defined take a single parameter:
			 *
		     *  1. `{*}` Data from the column cell to be prepared for ordering
			 *
			 * And return:
			 *
			 * * `{*}` Data to be sorted upon
			 *
			 * `{type}-asc` and `{type}-desc`: Functions are typical Javascript sort
			 * functions, taking two parameters:
			 *
		     *  1. `{*}` Data to compare to the second parameter
		     *  2. `{*}` Data to compare to the first parameter
			 *
			 * And returning:
			 *
			 * * `{*}` Ordering match: <0 if first parameter should be sorted lower
			 *   than the second parameter, ===0 if the two parameters are equal and
			 *   >0 if the first parameter should be sorted height than the second
			 *   parameter.
			 *
			 *  @type object

	 * * `number` - Will format numeric data (defined by `columns.data`) for

	 *   * `string` - Decimal point indicator
	 *   * `integer` - Number of decimal points to show
	 *   * `string` (optional) - Prefix.
	 *   * `string` (optional) - Postfix (/suffix).
	 * * `text` - Escape HTML to help prevent XSS attacks. It has no optional
	 *   parameters.
	 *
	 * @example
	 *   // Column definition using the number renderer

/**
 * Responsive is a plug-in for the DataTables library that makes use of
 * DataTables' ability to change the visibility of columns, changing the
 * visibility of columns so the displayed columns fit into the table container.
 * The end result is that complex tables will be dynamically adjusted to fit
 * into the viewport, be it on a desktop, tablet or mobile browser.
 *
 * Responsive for DataTables has two modes of operation, which can used
 * individually or combined:
 *
 * * Class name based control - columns assigned class names that match the
 *   breakpoint logic can be shown / hidden as required for each breakpoint.
 * * Automatic control - columns are automatically hidden when there is no
 *   room left to display them. Columns removed from the right.
 *
 * In additional to column visibility control, Responsive also has built into
 * options to use DataTables' child row display to show / hide the information
 * from the table that has been hidden. There are also two modes of operation

 * RowReorder provides the ability in DataTables to click and drag rows to
 * reorder them. When a row is dropped the data for the rows effected will be
 * updated to reflect the change. Normally this data point should also be the
 * column being sorted upon in the DataTable but this does not need to be the
 * case. RowReorder implements a "data swap" method - so the rows being
 * reordered take the value of the data point from the row that used to occupy
 * the row's new position.
 *
 * Initialisation is done by either:
 *
 * * `rowReorder` parameter in the DataTable initialisation object
 * * `new $.fn.dataTable.RowReorder( table, opts )` after DataTables
 *   initialisation.

/**
 * Scroller is a virtual rendering plug-in for DataTables which allows large
 * datasets to be drawn on screen every quickly. What the virtual rendering means
 * is that only the visible portion of the table (and a bit to either side to make
 * the scrolling smooth) is drawn, while the scrolling container gives the
 * visual impression that the whole table is visible. This is done by making use
 * of the pagination abilities of DataTables and moving the table around in the
 * scrolling container DataTables adds to the page. The scrolling container is
 * forced to the height it would be for the full table display using an extra
 * element.
 *
 * Note that rows in the table MUST all be the same height. Information in a cell
 * which expands on to multiple lines will cause some odd behaviour in the scrolling.
 *
 * Scroller is initialised by simply including the letter 'S' in the sDom for the
 * table you want to have this feature enabled on. Note that the 'S' must come
 * AFTER the 't' parameter in `dom`.
 *
 * Key features include:
 *   <ul class="limit_length">
 *     <li>Speed! The aim of Scroller for DataTables is to make rendering large data sets fast</li>
 *     <li>Full compatibility with deferred rendering in DataTables for maximum speed</li>
 *     <li>Display millions of rows</li>
 *     <li>Integration with state saving in DataTables (scrolling position is saved)</li>
 *     <li>Easy to use</li>

/*

Select is a collection of API methods, event handlers, event emitters and
buttons (for the `Buttons` extension) for DataTables. It provides the following
features, with an overview of how they are implemented:

## Selection of rows, columns and cells. Whether an item is selected or not is
   stored in:

* rows: a `_select_selected` property which contains a boolean value of the
  DataTables' `aoData` object for each row
* columns: a `_select_selected` property which contains a boolean value of the
  DataTables' `aoColumns` object for each column
* cells: a `_selected_cells` property which contains an array of boolean values
  of the `aoData` object for each row. The array is the same length as the
  columns array, with each element of it representing a cell.

This method of using boolean flags allows Select to operate when nodes have not
been created for rows / cells (DataTables' defer rendering feature).

## API methods

A range of API methods are available for triggering selection and de-selection
of rows. Methods are also available to configure the selection events that can
be triggered by an end user (such as which items are to be selected). To a large
extent, these of API methods *is* Select. It is basically a collection of helper
functions that can be used to select items in a DataTable.

Configuration of select is held in the object `_select` which is attached to the
DataTables settings object on initialisation. Select being available on a table
is not optional when Select is loaded, but its default is for selection only to
be available via the API - so the end user wouldn't be able to select rows
without additional configuration.

The `_select` object contains the following properties:

```
{
	items:string       - Can be `rows`, `columns` or `cells`. Defines what item
	                     will be selected if the user is allowed to activate row
	                     selection using the mouse.
	style:string       - Can be `none`, `single`, `multi` or `os`. Defines the
	                     interaction style when selecting items
	blurable:boolean   - If row selection can be cleared by clicking outside of
	                     the table
	toggleable:boolean - If row selection can be cancelled by repeated clicking
	                     on the row
	info:boolean       - If the selection summary should be shown in the table
	                     information elements
}
```

In addition to the API methods, Select also extends the DataTables selector
options for rows, columns and cells adding a `selected` option to the selector
options object, allowing the developer to select only selected items or
unselected items.

## Mouse selection of items

Clicking on items can be used to select items. This is done by a simple event
handler that will select the items using the API methods.
