minor refactoring to take distance to queried point into account
minor API fix
introduced getWayGeometry with base + adjacent node geometry option
implemented wayGeometry for both parts of the closest edge (LocationIDResult)
it is still possible to use miles but avoid it even for US+UK
fixing PointList.equals
remove the generic API glitch via new class GHPoint
made calcPoints optional
EdgeExplorer can return different EdgeIterator if necessary
