Changes (by SimonKing):
* status: needs_work => needs_review
* work_issues: Implement is_integral_domain and probably other small
stuff =>
Comment:
The reason of the error was that `FreeModule` tries (among other things)
the method `is_integral_domain()`. By default, it raises a
`NotImplementedError`, and this is the error we get above.
Proposed solution: Catch that `NotImplementedError` and do as if
`is_integral_domain()` had returned `False`.
I don't know if there will be further problems, but I'll put it back to
"needs review".
