traverse calculations and other unknown UDFs

> Currently simplification concentrates on basic constructs (and/or/=/...), but if it encounters an UDF which is not known; the recursion is stopped.
> For example the following expression is not simplified:
> {code:java}
> @Test public void testSimplifyRecurseIntoArithmetics() {
> checkSimplify(
> plus(literal(1),
> case_(
> falseLiteral, literal(1),
> trueLiteral, literal(2),
> literal(3))),
> "+(1, 2)");
> }
> {code}
