/**
 * Creates a grid of rectangular polygons with width and height consistent in degrees
 *
 * @function
 * @param {BBox} bbox extent of grid in [minX, minY, maxX, maxY] order.  If the grid does not fill the bbox perfectly, it is centered.
 * @param {number} cellWidth width of each cell, in units
 * @param {number} cellHeight height of each cell, in units
 * @param {Object} [options={}] Optional parameters
 * @param {Units} [options.units='kilometers'] the units of the cell width and height value.
 * Supports all valid Turf {@link https://github.com/Turfjs/turf/blob/master/packages/turf-helpers/README_UNITS.md Units}.
 * If you are looking for rectangles with equal width and height in linear units (e.g. kilometers) this is not the module for you.
 * The cellWidth and cellHeight is converted from units provided to degrees internally, so the width and height of resulting polygons will be consistent only in degrees.
 * @param {Feature<Polygon|MultiPolygon>} [options.mask] if passed a Polygon or MultiPolygon,
 * the grid Points will be created only inside it
 * @param {Object} [options.properties={}] passed to each point of the grid
 * @returns {FeatureCollection<Polygon>} a grid of polygons
 * @example
 * var bbox = [-95, 30 ,-85, 40];
 * var cellWidth = 50;
 * var cellHeight = 20;
 * var options = {units: 'miles'};
 *
 * var rectangleGrid = turf.rectangleGrid(bbox, cellWidth, cellHeight, options);
 *
 * //addToMap
 * var addToMap = [rectangleGrid]
