authl.handlers.email_addr: Email validation handler

This package provides a handler called EmailAddress which allows users to authenticate via a magic link sent to them via email.

    """ Generate an EmailAddress handler from the provided configuration dictionary.

    Possible configuration values (all optional unless specified):

Complex configuration

There are more complex options for providing your own sendmail routines et al but those will have to wait until I have a better documentation system in place.
