// AP - This replaces the std::unordered_set used in Level.h
// The problem with the original system is that it calls malloc for every insert it does. Not only is that expensive in itself but it also
// clashes with any other mallocs on other threads (specifically the large amount of mallocing being done in MobSpawner for the std::unordered_map)
// causing huge stalls.
// This isn't really a univeral replacement for std::unordered_set and is quite specific to Level.h
