JavaScript utilities to create .XKT files

/**
 * @desc Creates box-shaped triangle mesh geometry arrays.
 *
 * ## Usage
 *
 * In the example below we'll create an {@link XKTModel}, then create an {@link XKTMesh} with a box-shaped {@link XKTGeometry}.
 *
 * [[Run this example](http://xeokit.github.io/xeokit-sdk/examples/#geometry_builders_buildBoxGeometry)]
 *
 * ````javascript
 * const xktModel = new XKTModel();
 *
 * const box = buildBoxGeometry({
 *     primitiveType: "triangles" // or "lines"
 *     center: [0,0,0],
 *     xSize: 1,  // Half-size on each axis
 *     ySize: 1,
 *     zSize: 1
 * });
 *
 * const xktGeometry = xktModel.createGeometry({
 *      geometryId: "boxGeometry",
 *      primitiveType: box.primitiveType,
 *      positions: box.positions,
 *      normals: box.normals,
 *      indices: box.indices
 * });
 *
 * const xktMesh = xktModel.createMesh({
 *      meshId: "redBoxMesh",
 *      geometryId: "boxGeometry",
 *      position: [-4, -6, -4],
 *      scale: [1, 3, 1],
 *      rotation: [0, 0, 0],
 *      color: [1, 0, 0],
 *      opacity: 1
 * });
 *
 * const xktEntity = xktModel.createEntity({
 *      entityId: "redBox",
 *      meshIds: ["redBoxMesh"]
 *  });
 *
 * xktModel.finalize();
 * ````
 *
 * @function buildBoxGeometry
 * @param {*} [cfg] Configs
 * @param {Number[]} [cfg.center]  3D point indicating the center position.
 * @param {Number} [cfg.xSize=1.0]  Half-size on the X-axis.
 * @param {Number} [cfg.ySize=1.0]  Half-size on the Y-axis.
 * @param {Number} [cfg.zSize=1.0]  Half-size on the Z-axis.
 * @returns {Object} Geometry arrays for {@link XKTModel#createGeometry} or {@link XKTModel#createMesh}.
