// *     get globalizer options
// *    will return siblings of object specified by globalizer path
// *    This is useful for the globalizer control, which is a select/dropdown and needs to know the siblings of current selection
// *
// *     admin api endpoint admin_api/get_globalizer_options
// *    @param {string} sid - session id stored in cookie on client
// *    @param {string} globalizer_string - path to the global object
// *    @return {response} - success boolean and array with options
// *
// *    example:

// *        {
// *            toys: {
