/* 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.
*
* Authors:
* TBL Tim Berners-Lee, WorldWideWeb project, CERN
