* set and store highway and access classification for the turn function * expose highway turn classification and access turn classification and speed to the lua profile turn function * expose whether connection road at turn is incoming or outgoing * add lua tests for exposed information to turn function * update docs about attributes in process_turn * add turn_classification info to docs * adding warning if uturn and intersection dont match * handle u turns that do not turn into intersection[0] * split OSM link generation in an accessible coordinate function
