/**
 * Takes a {@link GeoJSON} object and returns a simplified version. Internally uses the 2d version of
 * [simplify-js](http://mourner.github.io/simplify-js/) to perform simplification using the Ramer-Douglas-Peucker algorithm.
 *
 *
 * @function
 * @param {GeoJSON} geojson object to be simplified
 * @param {Object} [options={}] Optional parameters
 * @param {number} [options.tolerance=1] simplification tolerance
 * @param {boolean} [options.highQuality=false] whether or not to spend more time to create a higher-quality simplification with a different algorithm
 * @param {boolean} [options.mutate=false] allows GeoJSON input to be mutated (significant performance increase if true)
 * @returns {GeoJSON} a simplified GeoJSON
 * @example
 * var geojson = turf.polygon([[
 *   [-70.603637, -33.399918],
 *   [-70.614624, -33.395332],
