* Store the Argyle User ID for the current user in a model called
  `CbvFlow`.
* Create a CbvFlow controller to handle routing between those pages.

  have all the new dependencies and everything.
* Add some light testing of each page separately

The filename needs to end with _spec.rb for Rspec to discover and run
it.
