I have two questions about the use of ParameterTypes with ClassWithParameters: 1) What's the role of the *MC classes? Integer vs. IntegerMC, AnyClass vs. AnyClassMC, etc.? 2) I have a subclass of ClassWithParameters where one of the parameters needs to be of a specific class. I'm not sure which ParameterTypes class I should use; AnyClass, or Instance, or SubClass. From the reference documentation it's not clear to me how to properly use these.
