Thanks Anders.  The new code works correctly with all cases I've tried so far.

I was wondering if it would be possible to add a static factory method
for creating binary variables since it would make my code more
readable, e.g.

    public static Variable binary(final String aName){    	
    	return new Variable(aName).lower(ZERO).upper(ONE).integer(true);
    }


Best,
