com.google.collide.dto.WorkspaceTreeUpdate
A list of mutations to the workspace tree to perform.These get sent to the FE, applied to the file tree, and then broadcast to other active clients in the workspace. A rename is just a type of MOVE operation.

    // Check each selected node to make sure it can be moved.
    if (!isMoveAllowed(parentDirData)) {
      return;
    }


    WorkspaceTreeUpdate msg = fileTreeModel.makeEmptyTreeUpdate();
    for (int i = 0, n = nodesToMove.size(); i < n; i++) {
      FileTreeNode nodeToMove = nodesToMove.get(i);
      PathUtil targetPath = new PathUtil.Builder().addPath(parentDirData.getNodePath())
          .addPathComponent(FileTreeUtils.allocateName(
              parentDirData.<DirInfoImpl>cast(), nodeToMove.getName())).build();
      msg.getMutations().add(FileTreeUtils.makeMutation(Mutation.Type.MOVE,
          nodeToMove.getNodePath(), targetPath, nodeToMove.isDirectory(),
          nodeToMove.getFileEditSessionKey()));
