Grape.Array Class
An array class created with Grape.Class mixing all of the Array.prototype methods and some new utility. Some functions are modified (like slice) to return a new instance of the current class instead of a plain array. If you extend this class, these methods will return an instance of your class. In the future, we should create implementations of default methods for old browsers. Note that adding elements with indexing does not change the length property unlike the native Array.
