Detailed Description

MemoryArena is a map based subclass for class MemPool provides book-keeping to divy a large chunk of pre-allocated memory to avoid the overhead of malloc/free or cudaMalloc/cudaFree, etc.

get/give are the primary calls used by class MemPool to get aligned memory from the pool or give it back
