/**
* @class vtkSubCommunicator
* @brief Provides communication on a process group.
*
*
*
* 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.
*
*
* @bug
* 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.
*
* @sa
* vtkCommunicator, vtkMultiProcessController
*
* @par Thanks:
* This class was originally written by Kenneth Moreland (kmorel@sandia.gov)
* from Sandia National Laboratories.
