/*
   This class is the basis for encapsulating Query support such that
   CIMOperationRequestDispatcher.cpp is not to be changed for adding
   new/additional types of query support.

   New types of query support (like CQL) need to subclass
   CIMOperationRequestDispatcher as can be seen in WQLCIMOperatioRequestDispatcher.

   Also, QuerySupportRouter.cpp must be extended to recognize the
   CQL query language identifier and route the requests to the
   appropriate query language processor. The new query language processor
   has to be added to the pegserver library.

   In addition, ProviderManager2/QueryExpressionFactory.h has to be
   extended similarly.
