 This script will do several things:
 * The directories `cnn_stories_tokenized` and `dm_stories_tokenized` will be created and filled with tokenized versions of `cnn/stories` and `dailymail/stories`. This may take some time.
-* For each of the url lists `all_train.txt`, `all_val.txt` and `all_test.txt`, the corresponding tokenized stories are read from file, lowercased and written to serialized binary files `train.bin`, `val.bin` and `test.bin`, will be placed in the newly-created `finished_files` directory. This may take some time.
