make getEdgeProps possible without knowledge of the endNode
removed RawEdgeIterator: should be returned for edge creation, getEdgeProps without an endNode and getAllEdges, but this separate interface complicate to handle and incompatibility is harder to use
Merge branch 'master' of git+ssh://github.com/graphhopper/graphhopper
added allEdgesIter to access edge count easily; first nearly working location2nodes ntree
deleted Location2IDPreciseIndex as it will be replaced by Location2NodesNtree; fixed subnetwork bug in GHUtility.sortDFS
further work on location2id index, bresenham makes problems
made all tests passing for Location2NodesNtree; fixed it via reverse spatial key
fixing minor bug in GraphHopper api
better location2node index integration in OSMReader
renamed node to adjNode. closes #7
minor cleanup
replaced String.isEmpty with length == 0 which hopefully fixes #25
bug fix: in 'shift' calculation and dataAccess.setInt was before null check
better error check in location2index
only one node per edge
added wayPoints; tests pass
fixed bug that edges shouldn't be accessed if they're already removed
fixed osmtest
fixed bug while removing nodes: edges between removed nodes didn't get invalidated
fixing integration tests for new index
