	//	summary: 
	//		Create a feature-rich constructor from compact notation
	//	className:
	//		The name of the constructor (loosely, a "class")
	//		stored in the "declaredClass" property in the created prototype
	//	superclass:
	//		May be null, a Function, or an Array of Functions. If an array, 
	//		the first element is used as the prototypical ancestor and
	//		any following Functions become mixin ancestors.
	//	props:
	//		An object whose properties are copied to the
	//		created prototype.
	//		Add an instance-initialization function by making it a property 
	//		named "constructor".
	//	description:
	//		Create a constructor using a compact notation for inheritance and
	//		prototype extension. 
	//
	//		All superclasses (including mixins) must be Functions (not simple Objects).
	//
	//		Mixin ancestors provide a type of multiple inheritance. Prototypes of mixin 
	//		ancestors are copied to the new class: changes to mixin prototypes will
	//		not affect classes to which they have been mixed in.
	//
	//		"className" is cached in "declaredClass" property of the new class.
	//
	//	example:
	//	|	dojo.declare("my.classes.bar", my.classes.foo, {
	//	|		// properties to be added to the class prototype
	//	|		someValue: 2,
	//	|		// initialization function
	//	|		constructor: function(){
	//	|			this.myComplicatedObject = new ReallyComplicatedObject(); 
	//	|		},
	//	|		// other functions
	//	|		someMethod: function(){ 
	//	|			doStuff(); 
	//	|		}
	//	|	);
