Working on expanding IOs query-ability

* Figured out how __save() should work in respect to revisions (see help(tamactiluya.io.IO.__save))
* I'm still trying to decide if I want to delete the .idea shit I get from PyCharm.
Working on modularity

* Using app factory pattern (no side-effects on import, like a sane
  person would)
* Planning on turning `IO` into a flask extension
    * Speaking of `IO`, I'm still not entirely sure how I want to model
      the system. Using directories for organization makes sense from
      a developers perspective (both for command line management and
      clean urls), but not so much from a users prospective. For example,
      creating WikiLinks to deeply nested articles means having to
      memorize (or at least copy/paste) the entire wikipath. I could
      dynamically populate the path, but that would create a lot of
      unneccessary complexity. WikiCategories (ala Cat:Article) might
      make more sense, and could be represented using directories.
* I'm dropping all semblence of MarkDoc compatibility; there are some
  good ideas in there, but being compatible doesn't make any sense. (An
  import process might, though)
