<!-- How about this?

This is super contrived. It's complex enough, however, to settle some of my concerns about Angular
(or any client-side framework). Basically, I want to see this with as little view logic as possible.

Overview:

A user is dropped into a two-step setup process: 1) account setup, and 2) spending categories setup.
When he completes those two steps, the group of accounts and group of categories should get moved to
a Home screen, where this little problem ends, but hypothetically he begins managing his finances.
