- Converts some initialization funcs to methods
- Exports funcs and methods needed for intialization
- In general, moves a ton of stuff around
Overall, this should maintain all existing functionality, but with the
ability to now better manage a WF instance.

now happens there.
This is the first step towards making `writefreely` usable as a
standalone package.
