[SPIIP-70] SQL database utilities
Create a new class, GwdcDb, to manage connections to the Swinburne SQL database. This also encompasses:
- adding extra dependencies (pyodbc, MS SQL ODBC driver, unix odbc)
- creating three example scripts to show usage
Note that you will need to either pass the username and password to GwdcDb when connecting, or create a file called 'gwdc_db_password' in your home directory containing the password for the 'gwdc_admin' account.
