Function setAllMatching

plugins/filltraffic.cpp:273–330

Helper function for writing new functions that check every tile on the map. newTraffic is the traffic designation to set. check takes a coordinate and the map cache as arguments, and returns true if the criteria is met. minCoord and maxCoord can be used to specify a bounding cube.
