Work done:
- created CreateList.java test in tests package, which tests for list
creation from 'Create new list' screen
- adapted CreateNewListScreenController.java to include SQL connection
and list creation

Problems faced:
- none so far

Work to be done:
- test CreateList.java needs to be checked
- user input (name of the list) needs to be validated
- chosen list name should be passed on to HomeScreen so that it can be
displayed on screen
