/**
* ArrayStack is a MutableStack which contains a FastList of data. ArrayStack iterates from top to bottom (LIFO order).
* It behaves like FastList in terms of runtime complexity. The method push() is amortized constant time like
* FastList.add(). The backing data structure grows and shrinks by 50% at a time, and size is constant. ArrayStack does
* not extend Vector, as does the Java Stack, which was one of the reasons to create this data structure.
