//              To implement new MI commands derive a new command class from the command base
//              class. To enable the new command for interpretation add the new command class
//              to the command factory. The files of relevance are:
//                  MICmdCommands.cpp
//                  MICmdBase.h / .cpp
//                  MICmdCmd.h / .cpp
//              For an introduction to adding a new command see CMICmdCmdSupportInfoMiCmdQuery
//              command class as an example.
