Assembles all the logics and comorphisms into a graph.

The modules for the Grothendieck logic are logic graph indepdenent,

and here is the logic graph that is used to instantiate these.

Since the logic graph depends on a large number of modules for the

individual logics, this separation of concerns (and possibility for

separate compilation) is quite useful.
