Updated the code for getPastMeeting to use a different date compare as
this wasn't working when the test was created. Also finished the procedure
to add notes to a meeting
Added the tests for addMeetingNotes and getPastMeeting
Added a new check to see if a contact exists by the ID and this is used in
getContacts to raise an error for a contact that doesnt exist
Added some print statements to show when the test is running
