MPICommand mpiCommandCreate(MPICommandType   type,
                             MPICommandParams *params,
                             const char       *label) 

CommandCreate creates a Command object. The command type is specified by type. The type-specific parameters are specified by params. If label is not Null (i.e., something meaningful), then branch commands can call this Command (by using the label). CommandCreate is the equivalent of a C++ constructor.
