Revised syntax of Form class. Added composer.json to take care of autoloading. Deleted old documentation in favor of markdown (this will need to be updated after code is revamped.
Added field interface and field class shells.
Moved field-specific stuff into their classes -- things are a bit hacked right now, but things are landing in the right places.
Got rid of 'position' element. I want to integrate this again, but in a better way.
