migration-to-create-initial-models

Now watch how Hobo can create a single migration for all of these:

    $ hobo generate migration

When the migration generator asks you

    What now: [g]enerate migration, generate and [m]igrate now or [c]ancel?

Choose `m` to both generate the migration and apply it to your
database.   We entered `initial_models` as the name for our
migration.

Now you can start your application

    $ rails server

You can access it via your web browser at `http://localhost:3000`.
It's not a polished UI of course, but we do actually have a working
application. Make sure you are logged in as an administrator (e.g. the
user who signed up first), and spend a few minutes populating the app
with projects, stories and tasks.

With some more very simple changes, and without even touching the
views, we can get surprisingly close to a decent UI.
