* ||| Array wrapper for custom prototype functionality |||
*
* ----------------------------------------------------
* Usage: A(myArr).loop() - or - A([1,2,3]).loop()
* ----------------------------------------------------
*
* Functions available:
* =====================
* A(a).getUnique() - - - - (array) unique elements from the original array
* A(a).contains(b) - - - - (bool) whether b exists in a
* A(a).has(b) - - - - - - (bool) alias for .contains()
* A(a).loop(f) - - - - - - (mixed) runs function f for every element in array a, passes params (value,key,array)
* A(a).wrapAll() - - - - - (object) makes any method from now on, that would have returned an array, return the array in this wrapper ( returns this for chained inst, e.g. var ar = A([]).wrapAll() )
*
* Plus polyfills for all new methods (every,forEach,some,map,filter,indexOf,lastIndexOf)
