+ File       : MemoryManager.h
+ Function   : Reserves large blocks of memory and gives pointers to small
+              portions of that block when requested.
+              This improves performance since a unique "LARGE ALLOCATION"
+              of memory is needed (a unique call to malloc).
+              It is also responsible of freeing memory.
+ Last change: 10/03/2004
+ Purpose    : Improve hash performance.
