What: tables-to-formula.txt

When: May 17, 2002

Where: Class.c, Structs.h

Why: This patch changes all the tables in class.c to formulas to make it easier for
  adding new levels and stuff like that.

How:
-----------------------------------------------------------------------------------------
@@ Open structs.h and search for:

#define LVL_IMPL

@@ Change all the level defines to:

#define LVL_MAX     100
#define LVL_IMPL	  (LVL_MAX + 4)
#define LVL_GRGOD	  (LVL_MAX + 3)
#define LVL_GOD		  (LVL_MAX + 2)
