/*                      Atoms: Names to numbers                 HTAtom.h
**                      =======================
**
**      Atoms are names which are given representative pointer values
**      so that they can be stored more efficiently, and compaisons
**      for equality done more efficiently.
**
**      HTAtom_for(string) returns a representative value such that it
**      will always (within one run of the program) return the same
**      value for the same given string.
