Basic rendering implemented
Need to think about editing
- Store tokens as a tree
  - How?
- Rendered blocks turn into textarea w/ raw property
- On unfocus, run new raw through lexer
- Surgically update tree with new node
- Queue a file save
  - Construct raw from 1-depth tree concat
- Track key presses (enter, bsp, arrows)
  - Enter needs to be aware of cursor line no. in block, if enter out it needs to update DOM properly
