Process for copying archived files to central google drive

Added a processing server program for copying archived files from personal
google drive to the central google drive. The program also updates the
fusion table's date_processed and central_data_store_uri fields.

A wrapper script was added so that the program runs every 24 hours. This
wrapper script also manages log files.

The program will be deployed using Docker. The process has been documented.

This resolved issue #309.
