Function strictlyLess

include/extractor/road_classification.hpp:169–177

LHS road classification is strictly less than RHS, if it belongs to a lower general category of roads. E.g. normal city roads are strictly less of a priority than a motorway and alleys are strictly less than inner-city roads.
