/**
 * Creates a circular sector of a circle of given radius and center {@link Point},
 * between (clockwise) bearing1 and bearing2; 0 bearing is North of center point, positive clockwise.
 *
 * @function
 * @param {Coord} center center point
 * @param {number} radius radius of the circle
 * @param {number} bearing1 angle, in decimal degrees, of the first radius of the sector
 * @param {number} bearing2 angle, in decimal degrees, of the second radius of the sector
 * @param {Object} [options={}] Optional parameters
 * @param {string} [options.units='kilometers'] miles, kilometers, degrees, or radians
 * @param {number} [options.steps=64] number of steps
 * @param {Properties} [options.properties={}] Translate properties to Feature Polygon
 * @returns {Feature<Polygon>} sector polygon
 * @example
 * var center = turf.point([-75, 40]);
 * var radius = 5;
 * var bearing1 = 25;
 * var bearing2 = 45;
 *
 * var sector = turf.sector(center, radius, bearing1, bearing2);
