How to use the @pylonide/jsdav/lib/shared/util.splitPath function in @pylonide/jsdav

putStream: function(handler, type, callback) {
    var path = this.path;
    // is it a chunked upload?
    var size = handler.httpRequest.headers["x-file-size"];
    if (size && size !== "undefined") {
      var parts = Util.splitPath(this.path);
      if (!handler.httpRequest.headers["x-file-name"])
        handler.httpRequest.headers["x-file-name"] = parts[1];
      handler.server.tree.getNodeForPath(parts[0], function(err, parent) {
        if (err)
          return callback(err);

        parent.writeFileChunk(handler, type, callback);
      });
    }
    else {
      this.vfs.mkfile(path, {}, function(err, meta) {
        if (err) {
          if (err.code == "EACCES")
            err = new Exc.Forbidden("Permission denied to write file:" + path);
          return callback(err);
        }

getName: function() {
    return Util.splitPath(this.path)[1];
  },

setName: function(name, callback) {
    var parentPath = Util.splitPath(this.path)[0];
    var newName    = Util.splitPath(name)[1];

    var newPath = parentPath + "/" + newName;
    var self = this;
    this.vfs.rename(newPath, {from: this.path}, function(err) {
      if (err)
        return callback(err);
      self.path = newPath;
      callback();
    });
  },
