Start the IPython Engine.
Start the engine, by creating it and starting the Twisted reactor.
This method does:
- If it exists, runs the mpi_import_statement to call MPI_Init
- Starts the engine logging
- Creates an IPython shell and wraps it in an EngineService
- Creates a foolscap.Tub to use in connecting to a controller.
- Uses the tub and the EngineService along with a Foolscap URL (or FURL) to connect to the controller and register the engine with the controller
