Detailed Description

Interface class to translate objects to a MPI_Datatype, void* and size used for MPI calls.

Furthermore it can be used to resize the object if possible. This makes it possible to receive a message with variable size. See Communication::rrecv.

To 'register' a new dynamic type for MPI communication specialize MPIData or overload getMPIData.
