-/*----- Revision history --------------------------------------------------* 
- *
- * $Log: group.h,v $
- * Revision 1.3  2004/04/04 19:04:11  mdw
- * Raw I/O of elliptic curve points and group elements.
- *
- * Revision 1.2  2004/04/03 03:32:05  mdw
- * General robustification.
- *
- * Revision 1.1  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.
- * Generally ensure that negative exponents do inversion correctly.  Add
- * table of standard prime-field subgroups.  (Binary field subgroups are
- * currently unimplemented but easy to add if anyone ever finds a good one.)
