* Add MPI::Status methods Set_elements() and Set_cancelled() * Added a bunch of comments in various places in the MPI C++ bindings implementatio just to explain what's going on (because C++ can hide a lot from you) * Insert C++ callbacks for the MPI_Grequest callback functions registered by MPI::Grequest::Start(). These callbacks keep a little meta-data (created by Grequest::Start()) that allow the proper callback signatures from C (i.e., from ompi_grequest_<foo>() in libmpi.a -- C code), translate arguments as required, and then invoke the callbacks with proper C++ signatures (i.e., call user-defined callbacks with C++ function signatures).
