DijkstraOneToManyRef
added methods for CH in DijkstraOneToManyRef and replaced all references... seems to work
testing CH with turn restrictions
added original edgeIds in LevelGraph, which are used to prevent u turns even when shortcuts are involved
fixing TR with CH + increased visibilty
hack to find out when an EdgeIterator represents a EdgeSkipIterState or not
logging
fixed /NodesShouldHaveStillAtLeastOneEdgeTest
merged turn_costs_1tomanyref
