* $Log$
* Revision 1.2 2006/02/16 16:47:14 cgruber
* Move some classes in to "internal" packages and re-work imports, etc.
*
* Also use UnsupportedOperationExceptions where appropriate, instead of WotonomyExceptions.
*
* Revision 1.1 2006/02/16 13:19:57 cgruber
* Check in all sources in eclipse-friendly maven-enabled packages.
*
* Revision 1.2 2003/08/11 18:17:41 chochos
* decoding of objects now works properly
