Guiding principle: put as much in the URL as is reasonable.
Things that happen:
Worksheet:
evaluate_code(input)
- -- introspection -- interacts
get_output(uid)
- create cells
- delete cells
- join cells
- split cells
- promote/demote cells in a cell heirarchy
- publish
- share
- delete
Cell:
- change input
- evaluate
get_output(start=0)
-- start - offset telling how much text we've already received -- output: {'status': ---, 'output': ---}
- update metadata: hide, lock, cell priority...
