/// source 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.
