Should our ARDs include the a class of the function that made them?

I think this will be more helpful for the statistical methods in cardx. For example, if we wanted to make an ARD-first function to create survival curves, it would be easier if the object passed was clearly identified via class as a survival ARD object (i.e. we could write ggplot2::fortify() methods for it).
