/*
* Winter JavaScript foundation library.
*
* Base class for Winter CMS back-end classes.
*
* The class defines base functionality for dealing with memory management
* and cleaning up bound (proxied) methods.
*
* The base class defines the dispose method that cleans up proxied methods.
* If child classes implement their own dispose() method, they should call
* the base class dispose method (see the example below).
*
* Use the simple parasitic combination inheritance pattern to create child classes:
*
* var Base = $.wn.foundation.base,
* BaseProto = Base.prototype
*
* var SubClass = function(params) {
* // Call the parent constructor
* Base.call(this)
* }
*
* SubClass.prototype = Object.create(BaseProto)
* SubClass.prototype.constructor = SubClass
*
* // Child class methods can be defined only after the
* // prototype is updated in the two previous lines
*
* SubClass.prototype.dispose = function() {
* // Call the parent method
* BaseProto.dispose.call(this)
* };
*
