// AcDbGroup
//
// Maintains an ordered collection of database objects with a related iterator.
// An iterator can be obtained via an existing AcDbGroup object with
// the newIterator() method.  See below for class descriptions for both
// AcDbGroup and AcDbGroupIterator.
//
// AcDbGroup objects are contained in a special group table (actually a
// dictionary).  This dictionary can be obtained like this:
//
//     AcDbDictionary* pGrpDict = 
//         acdbHostApplicationServices()->workingDatabase()->groupTable();
//
// The AcDbGroup constructor does not add the group to the group dictionary;
// this must be done explicitly, using the AcDbDictionary protocol.
//
// When an entity is erased, it is automatically removed from
// the groups that contain it.
