Adding spec for initial user profile

When a user first logs in, they need to approve of the terms, then be
asked to fill in a rudimentary user profile. This profile has 3 parts:

1) Logistical information for reauthenticating with CurateND once they
no longer have an ND NetID

AND

2) Scholarly information that might be helfpul for citation generation.

AND (possibly)

3) Keys to allow us to push information to other channels (i.e. Twitter,
Google+, Facebook, etc.).
