This manages the whole MPI Environment and the first constructed instance is responsible for calling MPI_Init and MPI_Finalize.
It must be constructed near the start of program execution and destructed near the end.
Constructing/destructing other instances has no effect.
It offers Initialized and Finalized methods equivalent to MPI_Initialized/MPI_Finalized.
