rename method

Future<File> rename (String newPath)

Renames this file. Returns a Future<File> that completes with a File instance for the renamed file.

If newPath identifies an existing file, that file is replaced. If newPath identifies an existing directory, the operation fails and the future completes with an exception.

Implementation
