Comment (by SimonKing):

 It could be that I will rewrite everything from scratch. Reason: Volker
 gave some good arguments on [https://groups.google.com/forum/#!topic/sage-
 devel/xMSPed6C0ds sage-devel] why I should not use C structs for the terms
 on `PyObject*` for the coefficients (even though it seems I got the
 reference counting right...), but should rely on Python objects. It could
 be that I'll end up implementing an element of a path algebra as a typed
 memoryview...

 We will see.
