      NodeLoader<? extends L> createNodeLoader(K key)
      Create a node loader that knows how to load nodes for items that are specified by the given key. The key can be almost anything. The interpretation of it is entirely up to the factory implementation.
      Parameters:
      key - A key that can be used to identify which items the node loader should load
      Returns:
      A node loader object
