// .NAME vtkSocketController - Process communication using Sockets
// .SECTION Description
// This is a concrete implementation of vtkMultiProcessController.
// It supports one-to-one communication using sockets. Note that
// process 0 will always correspond to self and process 1 to the
// remote process. This class is best used with ports.
