/**
* Implements prototypical inheritance by replacing the prototype of one constructor with the prototype of another constructor.
*
* @param ctor - constructor which will inherit
* @param superCtor - super (parent) constructor
* @throws first argument must be either an object or a function which can inherit
* @throws second argument must be either an object or a function from which a constructor can inherit
* @throws second argument must have an inheritable prototype
* @returns child constructor
*
* @example
* function Foo() {
* return this;
* }
* Foo.prototype.beep = function beep() {
* return 'boop';
* };
*
* function Bar() {
* Foo.call( this );
* return this;
* }
* inherit( Bar, Foo );
*
* var bar = new Bar();
* var v = bar.beep();
* // returns 'boop'
