Well, as complete as it could be without proper automated testing.
I think there'll be some more testing soon, as it doesn't make sense
for it to hang out so blatantly like this.
Both a fmt and clippy pass have shaken all the lint off, and right
now it builds without warnings or lintings. Wheee!
This features all of the reference types that I commonly use,
including the ORG mode [[Title]], #CamelCase, #lisp-case, and #colon:case.
There are still edge cases around capitalization and the mixing of symbols
and numbers, and I'll have to hack on those until I'm satisfied.
