added exception in method getFutMeetList()
method seems to be done for now
added meetingSet to flush()
added meetingSet to load()
added meetingSet to constructor
added 'first-run' constructor to create empty sets
add static bool firstRun to load(), as if it checked for first run of program by seeing if a disk on file existed, then it would not know if a FileNotFound exception would be more appropriate
not sure about this static bool - may replace tomorrow
simplified return statements
wrote getFutureMeetingList(Calendar) method
edited to make sure only future meetings are considered
added method to return a list of meetings to avoid duplicated code in ContactManagerImpl
made method static as makes to sense to create an instance of meetingimpl just to call it
reimplemented methods without former levels of code repetition
added some comments
added @param explanation
added addNotes method to MeetingImpl so I can keep notes variable private
wrote addMeetingNotes method
