  """A user and associated login credentials, the fundamental identity entity.

  User is a separate Model class from Person because the same login
  ID may be used to, for example, serve as Contributor in one Program
  and a Reviewer in another.

  Also, this allows a Person to, in the future, re-associate that
  Person entity with a different Google Account if necessary.

  A User entity participates in the following relationships implemented
  as a db.ReferenceProperty elsewhere in another db.Model:

   persons)  a 1:many relationship of Person entities identified by the
     User.  This relation is implemented as the 'persons' back-reference
     Query of the Person model 'user' reference.

   documents)  a 1:many relationship of Document entities identified by the
     User.  This relation is implemented as the 'user' back-reference
     Query of the Document model 'user' reference.

   responses)  a 1:many relationship of Response entities submitted by the
     User.  This relation is implemented as the 'responses' back-reference
     Query of the Response model 'respondent' reference.
