Defined in:
app/services/browse_level_evaluation_service.rb

Overview

Purpose: To walk the browse levels until we reach the current browse level. While walking the browse levels, determine which FacetItems to attach at each level.

That is to say, each browse level’s “values” are lazily evaluated.

There is a complicated negotation of the Exhibit, Collection, BrowseLevel, and query params.

TODO: Should this class be implemented as a delegate of the

ApplicationController class. I am passing in three anonymous functions that
could instead be deferred to the calling context.
