*   Add `string_to_index_table`, which returns a lookup table that matches
    strings to indices.
*   Support restore session from checkpoint files in v2 in
    `contrib/session_bundle`.
*   Added a tf.contrib.image.rotate function for arbitrary angles.
*   Added `tf.contrib.framework.filter_variables` as a convenience function to
    filter lists of variables based on regular expressions.
