-"""Synchronize multiple files with a Google Storage Bucket and subdir.
-For a lack of a better word 'synchronization' was used, warnings:
-1) Downloads files that are not found locally
-2) Uploads files that are not found in the bucket
-3) Does NOT check version, date or content of the file. If the file is reported
-   to be present both locally and in the bucket, no upload nor download is
-   performed.
-4) If we find filenames that do not match our expectations, an exception
