* @class vtkProcess
* @brief a process that can be launched by a vtkMultiProcessController
*
* vtkProcess is an abstract class representing a process that can be launched
* by a vtkMultiProcessController. Concrete classes just have to implement
* Execute() method and make sure it set the proper value in ReturnValue.
*
* @par Example:
* class MyProcess: public vtkProcess
* ...
* vtkMultiProcessController *c;
* MyProcess *p=new MyProcess::New();
* p->SetArgs(argc,argv); // some parameters specific to the process
* p->SetX(10.0); // ...
* c->SetSingleProcess(p);
* c->SingleMethodExecute();
* int returnValue=p->GetReturnValue();
*
* @sa
* vtkMultiProcessController
