Facets present ways of narrowing down an item selection, by showing what the options are, and how many results will be produced.
This module does most of the legwork in setting up facets for collections.
The emphasis is on performance, at the occasional expense of memory.
Refer to tests.py for more examples of behaviour.
A FacetGroup is an ordered set of `FacetField`s on a particular collection.
A FacetField is an ordered set of `FacetLabel`s, plus a heading.
A FacetLabel contains the information necessary to render a single facet option, as part of a list or drop-down.
