=head1 DESCRIPTION

Validates that the input looks like an email address using L<Email::Valid>.
Widget type is 'text'.

If form has 'is_html5' flag active it will render <input type="email" ... />
instead of type="text"

This field has an 'email_valid_params' attribute that accepts a hash
reference of extra values passed to L<Email::Valid/address> when
validating email addresses.

If you want to preserve the case of the email address, set the
'preserve_case' attribute.
