turn by turn tracking data downloader and storage in sqlite3 db

This is the script I've been developing for myself to download and store the turn by turn data.

It is a bit rough, but works.
It does not have a lot of control flow: either it works or it doesn't, basically.

It takes a lot of time, mainly because of CASTOR being slow in making available the data for local storage.

The data in the controller file could also be retrieved directly from sixdeskenv, so the controller can be easily integrated with other routines that read the files from there. The only data in the input block that cannot be retrieved directly from sixdeskenv is the tunes variable value.

I hope this scripts can be a good starting point for developing a more detailed program to work with the turn by turn tracking data output of SixDesk.
