Integrated FLGP demo into WWI database

Added changes required to run Automatic tuning FLGP demo in WWI database.
1. Added new package type "Unknown" for one order line
2. Added one order line in the "Unknown" package
3. Updated AT demo script to work with WWI database.
4. Included PackageTypeID column in NCCI on OrderLines table.

Minor
1. Added .gitignore file for the local folder
2. Updated UI page for AT demo.
