00035 // Description: This file contains the class definition for ConstraintHandler.
00036 // ConstraintHandler is an abstract base class, i.e. no objects of it's
00037 // type can be created. ConstraintHandlers enforce the single and multi point 
00038 // constraints that exist in the domain by creating the appropriate FE_Element
00039 // and DOF_Group objects.
