LineString selection tool: you can select a part or a stretch of a polyline on the map. Performance-oriented, uses rbush for segment lookup

Look how this thing deals with a coastline polyline consisting of ~500 points

.disable() Disable control, remove handlers and selection

.reset() Reset selection

.selectMeters(startMeter, endMeter) Select stretch by meter distances from linestring start.

.toGeoJSON() Returns selection GeoJSON
