/**
* Takes a {@link Point} and a {@link LineString} and calculates the closest Point on the (Multi)LineString.
*
* @name nearestPointOnLine
* @param {Geometry|Feature<LineString|MultiLineString>} lines lines to snap to
* @param {Geometry|Feature<Point>|number[]} pt point to snap from
* @param {Object} [options={}] Optional parameters
* @param {string} [options.units='kilometers'] can be degrees, radians, miles, or kilometers
* @returns {Feature<Point>} closest point on the `line` to `point`. The properties object will contain three values: `index`: closest point was found on nth line part, `dist`: distance between pt and the closest point, `location`: distance along the line between start and the closest point.
* @example
* var line = turf.lineString([
* [-77.031669, 38.878605],
* [-77.029609, 38.881946],
* [-77.020339, 38.884084],
* [-77.025661, 38.885821],
* [-77.021884, 38.889563],
* [-77.019824, 38.892368]
* ]);
* var pt = turf.point([-77.037076, 38.884017]);
*
* var snapped = turf.nearestPointOnLine(line, pt, {units: 'miles'});
*
* //addToMap
* var addToMap = [line, pt, snapped];
* snapped.properties['marker-color'] = '#00f';
