   *  Note that this can result in slower response times or increased power consumption (with a GPS chip on a mobile device for example).

   * @param {number} [options.timeout] A positive long value representing the maximum length of time (in milliseconds) the device is allowed to take in order to return a position.
   *  The default value is Infinity, meaning that getCurrentPosition() won't return until the position is available.
   * @param {number} [options.maximumAge] A positive long value indicating the maximum age in milliseconds of a possible cached position that is acceptable to return.
   *  If set to 0, it means that the device cannot use a cached position and must attempt to retrieve the real current position.
   *  If set to Infinity the device must return a cached position regardless of its age. Default: 0.
