add streetless linking in threaded heuristic classes
simpletransfer: add serial id, forbid two in a row, weightLowerBound
threaded bidi heuristic: add abort method, remove cutoff parameter
do not clamp max transfers
add simplified single-itinerary path service
revise threaded heuristic (transit only, separate street searches)
set boarding costs and slack; stub path parser
fix exceptions in itinerary generator (should really use path parser)
add debug code
implement pathparser
walk more
remove double-transfer protection from simpleTransfer (use parser)
spew less output
remove hard-coded linking radius
remove hardcoded options, can be accomplished w/ prototypeRoutingRequest
add threaded bidi heuristic factory (static inner) class
[ken] otp-thirft build creates distro
[ken] fixes compilation error in graph_builder
Temporary fix.
