HTML::FormFu::Filter::CopyValue - copy the value from another field

       Carl Franks <cpan@fireartist.com>

       If the original field contains an invalid value (a value that will be constrained through a constraint)
       that invalid value will be copied to this field (the field with the CopyValue filter).  So, the user has
       to change two fields, or you can remove the invalid value in a custom constraint.
