* $Log$
* 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 1.4 2005/05/11 15:21:53 cgruber
* Change enum to enumeration, since enum is now a keyword as of Java 5.0
*
* A few other comments in the code.
*
* Revision 1.3 2003/08/08 00:44:04 chochos
* manage model groups for object store coordinators.
*
* Revision 1.2 2003/08/08 00:36:41 chochos
* add a little more functionality
*
* Revision 1.1 2003/08/07 02:42:28 chochos
* EOModel can read an .eomodeld file. EOModelGroup doesn't do much for now.
