Call cairo.get_include() to find py3cairo.h

See merge request count0/graph-tool!16

This returns the effective number of groups, taking into consideration
their sizes.

If pycairo was installed from source, py3cairo.h may not have been

itself where py3cairo.h is by calling cairo.get_include().

This adds the "dynamics" submodule, with implementation of several
dynamical processes.
