Our benchmarks tend to be organized either with the main class as a baseline benchmark with subclasses for all other types, or an abstract base class with an empty @param tag and subclasses for each actual benchmark.  `KeyAgreementBench.java` is done that way, and I personally like that approach better and changed this class to follow that model.  Either way is just fine though.  The important thing is that if you have parameters in the parent class, it should not match any parameter sets in the child classes or you just end up running the same benchmark twice.
