/**
* @file TwoHeadArena.c
*
* This file implements a simple general purpose double-ended stack allocator.
*
* A double-ended stack allocator accepts allocations at either the "head" or "tail" of its allotted memory region.
* While in general this type of allocator could accept deallocations on the most recently allocated block at either
* end, this implementation does not support any individual deallocations; the only provided way to deallocate anything
* is to reset the entire arena, deallocating everything. This scheme is most applicable to allocating similar data
* with identical lifetime.
