=head1 DESCRIPTION
This maps an individual column to a form element. The C<how> argument
can be used to force the field type into any you want. All that you need
is a method named "_to_$how" in your class. Your class inherits many from
-AsForm already. Override them at will.
+AsForm already.
If C<how> is specified but the class cannot call the method it maps to,
then AsForm will issue a warning and the default input will be made.
