Overview

This overloads the tainting methods in array with callbacks. So, I can block all changes to an array, or broadcast to observers after a change, or limit the size of an array. It really just opens up the array to one more dimension: change. Before and after change, stack up any activity to block or enhance the experience. There are also callbacks on untaint. The tainting methods actually
