Changes (by SimonKing):
* status: needs_work => needs_review
* work_issues: Do not allow conversion of an arrow that is not in the
quiver =>
Comment:
If I understand correctly, `_from_dict` is inherited, but `_monomial` is
dedicated to path algebras. And `A1._monomial(b)` should of course try to
convert b into an element of the underlying path semigroup, before
constructing an element of itself.
Anyway: Fixed and added as test, needs review...
