this is wierd. nestedSuites is the only instance data in this class, but it diesn't
seem to make sense to say two suites are the same if they have the same nested suites.
I guess if they have the same class and have the same nested suites, and subtypes agree,
then they are equal.

// This is interesting. Seems I could define a default hashcode based on
// properties that are actually methods in the trait. Like nestedSuites. Wierd.
