Paul Beckingham 1bf6c8a9fa Expressions
- DOM::get now returns the input name by default, rather than "", which
  was the cause of many filter elements not working.
- Modified Variant to have no private data, which means fewer copies of
  Variants and less code.
- Eliminated Variant::operator^ - not needed.
