overwrites a single property so it can still call super
can.Construct._overwrite = function(addTo, base, name, val) {
Check if we're overwriting an existing function
addTo[name] = isFunction(val) &&
isFunction(base[name]) &&
fnTest.test(val) ? (function(name, fn) {
return function() {
var tmp = this._super,
ret;
Add a new ._super() method that is the same method but on the super-class
this._super = base[name];
The method only need to be bound temporarily, so we remove it when we're done executing
ret = fn.apply(this, arguments);
this._super = tmp;
return ret;
};
})(name, val) : val;

overwrites an object with methods, sets up _super newProps - new properties oldProps - where the old properties might be addTo - what we are adding to
can.Construct._inherit = function(newProps, oldProps, addTo) {
addTo = addTo || newProps
for (var name in newProps) {
can.Construct._overwrite(addTo, oldProps, name, newProps[name]);
