Function map_model::make::match_points_to_lanes

pub fn match_points_to_lanes<F: Fn(&Lane) -> bool>(
    bounds: &Bounds, 
    pts: HashSet<HashablePt2D>, 
    lanes: &BTreeMap<LaneID, Lane>, 
    filter: F,

Snap points to an exact Position along the nearest lane. If the result doesn’t contain a requested point, then there was no matching lane close enough.
