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
isochrone class to calculate access sheds, i.e. the area that can be reached within n minutes
added debug code to be able to figure why some edges are traversed to fast (aside fromom u-shaped roads)
Don't use TSimpleServer. Not recommended for production. Use TThreadPoolServer instead since it is transport-compatible with our existing code.
Merge pull request #944 from mentaer/master

New isochrone class for OTP Analyst to calculate access sheds, such as walksheds.
