In some situation, we may have custom events For example, we may have a custom kernel event We can register the event through this method
function registerEvents() {
      var _ref = arguments.length > 0 && arguments[0] !== undefined ? arguments[0] : {},
          name = _ref.name,
          target = _ref.target;

      if (!name || !chimeeHelper.isString(name)) throw new Error('The event name must be a string, but not ' + (typeof name === 'undefined' ? 'undefined' : _typeof(name)));
      if (!target || !chimeeHelper.isString(target)) throw new Error('The event target must be a string, but not ' + (typeof target === 'undefined' ? 'undefined' : _typeof(target)));
      if (target === 'kernel') {
        kernelEvents.push(name);
      }
    }
