Memory pool manager for efficient instance allocation

The first class to handle memory allocation requests from external sources. Internally has an array of chunks, and since chunks has chunk, effectively manages all low-level memory-related classes.

pool lazily has chunks per allocatable size

A key point in creating a custom memory pool is increasing speed by listing same-size memory in one place. chunks has a block concept where each block can only allocate/ deallocate pre-specified sized memory. pool creates chunks with fixed block size. When external requests memory allocation of a specific size, pool finds chunks handling that block size. If none exist, creates lazily.
