    A Profile object instance contains information about an individual.

    This individual is a potential SciPost Contributor but is not necessarily registered.
    It is created and used by Admin, EdAdmin or other internal SciPost staff.

    For registered Contributors, a profile is initially created from the contributor-filled
    information in the Contributor object. Profile should thus be viewed as containing
    the Admin-certified version of this information.

    The information is only partial, and is meant to be used among others to:

    #. help with editorial matters:
       #. help EdAdmin identify prospective Fellows
       #. help Fellows identify appropriate referees
       #. mark potential conflicts of interest

    #. allow respecting people's preferences:
       #. mark somebody as not willing to receive emails from SciPost.
       #. mark somebody as a non-referee (if that person does not want to referee for SciPost)
