[Clops-users] enum

[Radu G. <rad...@gm...>]

I changed clops to maintain the order of enum values. The syntax for
the property "choices" of the type "enum" (and of the type
"enum-list") is now:
  choices="string1|string2(VALUE1),string3(VALUE2)"
You are guaranteed that VALUE1.compareTo(VALUE2) < 0. This is nice to
have if you use an enum to represent verbosity levels.

The syntax used to be:
  choices="string1(VALUE1),string2(VALUE1),string3(VALUE2)"
or
  choices="string1(VALUE1),string3(VALUE2),string2(VALUE1)"

I added as a task the check that values are unique.

Let me know if you see any problems with this, or if you like a
different syntax.
