TERMINOLOGY:
-- "slot" = A particular combination of tense/mood/person/number/etc.
Example slot names for verbs are "pres_1s" (present first singular) and
"subc_subii_3p" (subordinate-clause subjunctive II third plural).
Each slot is filled with zero or more forms.
-- "form" = The conjugated German form representing the value of a given slot.
-- "lemma" = The dictionary form of a given German term. For German, always the infinitive.

FIXME:
1. Handle fensterln. (DONE)
2. Handle spie- past tense of speien. (DONE)
3. Make sure rathen, verheirathen work. (DONE)
4. Modify einfix to better handle managen, framen. (DONE)
5. Use variant codes so variant imperatives with and without -e match up in conjoined verbs e.g. [[ausschneiden und einfügen]].
6. In conjoined verbs e.g. [[ausschneiden und einfügen]], don't repeat auxiliaries.
