Put differently, it creates a vector view of an x and a y value.

For `Vector` specific documentation, see `Vector`.

__init__(self, target, x_attribute, y_attribute)
(Constructor)

source code 

Construct a `BoundVector`

X and y attributes will be looked up on `target` with names
`x_attribute` and `y_attribute`.

Parameters:

    target
        the object to bind to. The object on which the x and y
        attributes reside.

    x_attribute :: string
        name of attribute of the x value on the target

    y_attribute :: string
        name of attribute of the y value on the target

Overrides: object.__init__
