/**
* Takes a set of {@link Point|points} and returns a concave hull Polygon or MultiPolygon.
* Internally, this uses [turf-tin](https://github.com/Turfjs/turf-tin) to generate geometries.
*
* @function
* @param {FeatureCollection<Point>} points input points
* @param {Object} [options={}] Optional parameters
* @param {number} [options.maxEdge=Infinity] the length (in 'units') of an edge necessary for part of the
* hull to become concave.
* @param {string} [options.units='kilometers'] can be degrees, radians, miles, or kilometers
* @returns {Feature<(Polygon|MultiPolygon)>|null} a concave hull (null value is returned if unable to compute hull)
* @example
* var points = turf.featureCollection([
* turf.point([-63.601226, 44.642643]),
* turf.point([-63.591442, 44.651436]),
* turf.point([-63.580799, 44.648749]),
* turf.point([-63.573589, 44.641788]),
* turf.point([-63.587665, 44.64533]),
* turf.point([-63.595218, 44.64765])
* ]);
* var options = {units: 'miles', maxEdge: 1};
*
* var hull = turf.concave(points, options);
*
* //addToMap
* var addToMap = [points, hull]
