@method forEach([fn], [scope])
@returns Nothing
@short Iterates over the array, calling [fn] on each loop.
@extra This method is only provided for those browsers that do not support it natively. [scope] becomes the %this% object.
@example

['a','b','c'].forEach(function(a) {
// Called 3 times: 'a','b','c'
});
