+// AP - This replaces the std::unordered_map used in MobSpawner.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 Level.h for the std::unordered_set)
+// causing huge stalls.
+// This isn't really a univeral replacement for std::unordered_map and is quite specific to MobSpawner.h
