/**
 * Modifed from SpatialHash
 *
 * Main differences are:
 * - Optimized grid size to ensure we only ever need to look +/-1 cell
 * - Aware of atomic radii and will only output atoms within rAtom + rExtra
 *   (see withinRadii method)
 *
 * (Uses rounding rather than bitshifting as consequence of arbitrary grid size)
 * @class
 * @param {Float32Array} atomsX - x coordinates
 * @param {Float32Array} atomsY - y coordinates
 * @param {Float32Array} atomsZ - z coordinates
 * @param {Float32Array} atomsR - atom radii
 * @param {Float32Array} min - xyz min coordinates
 * @param {Float32Array} max - xyz max coordinates
 * @param {Float} maxDistance - max distance
