Pull stop-finding logic for direct transfers out of the graph builder modules

this allows for a single graph builder module and reusing this logic elsewhere in OTP
add prototype for analyst profile routing on large frequency-based graphs

this begins splitting Profile Analyst (one to many profile routing) out from
one to one profile routing. the former does not need to reconstruct paths
and in many cases we can take advantage of routes being pure frequency-based.
