Changes from Dylan Stark to allow registration of topology

routines and introducing a physical to logical processor
mapping.

Now it is possible to register custom topology routines if
you don't like the two ones we have at the moment (the
traditional one and the new one from Frank Loeffler).

You can also provide routines to optimise the placement of
neighbouring processes on the processors by giving a custom
mapping from the numbers PUGH uses for the processors to
the actual MPI processor.

Please treat this registration as semi-volatile for the moment
and coordinate with Dylan if you fancy using it.
