> Being able to provide arguments to a comparator, to parametrize its behavior,
> can be useful.
> For example, a generic ReverseComparator is trivial to write, but without the
> ability to provide arguments at the comparator constriction, it cannot be
> used.
> CASSANDRA-2231 provides another use case for this.
> This ticket proposes to introduce a parser for comparator definition that
> supports optional parameters and to introduce a generic ReverseType as a
> simple example of this.
