Of all comparison operators, composite values only allow equality operators

[Veracity0]

With composites, allow "==", "!=", and "≈".
Other comparisons - "<", "<=", ">", ">=" - are meaningless and generate a compile-time error.

This simplifies things a lot: CompositeType no longer needs a compareTo method.
