First draft of classifying on arbitrary parameters instead of just answers.
TODO: also display parameter name in classification description; fix substitution hack (looking for "Answer" and substituting with param choice)
To ponder: does it still make sense to group rules into types of classifiers, and associate those with particular inputs/widgets?
Since we could now be comparing to arbitrary parameters instead of answers.
Or, should the comparison parameter choice happen on a per-classifier instead of per-rule basis? this would give less flexibility, but might make more sense with the classifier/rule breakdown.
Revert "First draft of classifying on arbitrary parameters instead of just answers."

We will revisit this functionality later, because it's actually a substantial change with changes to how classifiers function

This reverts commit 305a1b40b5e4f8f1f8f07ab3d26cd19fa9ebf4f8.
