/// file locations to their concrete addresses.
 
/// General Outline:
/// The AddressResolver is a Searcher.  In that protocol, the SearchFilter
/// asks the question "At what depth of the symbol context descent do you want
/// your callback to get called?" of the filter.  The resolver answers this
/// question (in the GetDepth method) and provides the resolution callback.
