Confirm users identity

[stretchyboy]

As we can't Oauth against school but we want to use school email addresses, maybe the best way is https://developer.mozilla.org/en-US/Persona/Quick_Setup

Persona should be used with a server creating a session but we are trying to build this out of static pages to work on schools servers so will try slightly modified.

On page load check if logged in, if not put up modal asking for email address (and name?) (prompt maybe from a load so you can configure it)
maybe http://kylefox.ca/jquery-modal/examples/index.html
take the name trigger a login
verify the assertion on page
on login continue the rest of the stuff (retrieving records or posting new ones)
