// .NAME vtkSubCommunicator - Provides communication on a process group.
//
// .SECTION Description
//
// This class provides an implementation for communicating on process groups.
// In general, you should never use this class directly. Instead, use the
// vtkMultiProcessController::CreateSubController method.
//
// .SECTION BUGS
//
// Because all communication is delegated to the original communicator,
// any error will report process ids with respect to the original
// communicator, not this communicator that was actually used.
//
// .SECTION See Also
// vtkCommunicator, vtkMultiProcessController
//
// .SECTION Thanks
// This class was originally written by Kenneth Moreland (kmorel@sandia.gov)
// from Sandia National Laboratories.
