-Fixed size allocator notes: As mentioned briefly in the tutorial you can enable and disable the

-Compilation notes:
-
-Microsoft Visual C++ : Confirmed working with version 8.0.50727 with some deprecation warnings
-I'm going to leave the deprecation warnings in so that it still works cleanly with GCC.

+FSA is just a simple memory pool that uses a doubly linked list of available nodes in an array. This is
