super basic auth

Not sure if this is the correct way of doing this, but this is the idea I had for managing potential changes:

* Do work in new branch ('review' was a little too general here)
* Push full (new) branch to origin
* Create pull request (?)
* Do code review
* Update, commit updates to branch, merge into master, commit to origin master

In terms of this specific pull request -- this is my very (very) basic attempt at authentication. Authentication, that is, that does not hit any sort of backend DB, but merely accepts all logins and allows one to view their username!
The ids here must match the keys in the loginForm tuple.
