Add node_modules/argieDB as submodule
Session is set when user accesses /start (no matter what)

/start with no cookie:
  create new profile
  save to db and get id
  set session to id
  set cookie 'profile' to id
  reply { mode: 'newShip' } // should change this to newProfile

/start with cookie:
  look up profile in db with id in cookie
  if exists:
    set session
    reply { mode: 'selectShip'}
  doesn't exist:
     reply { error: 'Cookie profile_id not found in db.'}
Rename test/testIndex.js to test/testIndexController.js
Remove PUT /profile
Add documentation to GET /start
WIP add POST /profile/:id
