+ * Normal basis support (translates to poly basis internally).  Rewrite

+ * for repeated constants.

  * Revision 1.2  2004/04/01 12:50:09  mdw
  * Add cyclic group abstraction, with test code.  Separate off exponentation
  * functions for better static linking.  Fix a buttload of bugs on the way.
