I will most probably try to expose all of the APIs available in
GMP as methods. For now, I'm focussing on getting the interactions
between the different types and the Python native number types
in sync.

One of the next releases will expose some kind of number formatting
method which will then also be used in pickling Integers (using
base-32 numbers).
