Overview
Overview
This class manages params and nesting of filter queries.
Each inheriting class defines a PARAMS variable. Each concern defines `self.params`. Together these two lists are used to compose a list of acceptable params, dynamically, based on the nature of the nested queries.
Test coverage is currently in /spec/lib/queries/otu/filter_spec.rb.
!! When adding a new query tests do some linting of parameters, constants etc. Run them early and often !!

We could consider `.safe_constantize` to make this a f(n), but we'd have to have a list somewhere else anyways to further restrict allowed classes.

Of interest, the previous native `merge()` (and `and()“) make things complicated:
For example a.merge(b) != b.merge(a) in some cases. This is because certain clauses are tossed without warning (notably `.from()`). See:
We presently use SQL with INTERSECTION to combine facets.

#permitted_params(hsh) ⇒ Object
This method is a preprocessor that discovers, by finding the nested subqueries, which params should be permitted. It is used to build a permitable profile of parameters.
That profile is then used in the actual .permit() call.
An alternate solution, first tried, is to permit the params directly during inspection for subqueries. This also would work, however there are some nice benefits to having a profile of the allowed params available as an Array, for example we can use it for API documentation a little easier(?!).
In essence what we needed was for ActionController::Parameters to be able to accumulate (remember) all permitted params (not just their actual data) over multiple .permit() calls. If we had that, then we could do something like params.permitted_params => Array after multiple calls like params.permit(:a), params.permit(:b).
any parameter set for the query.
