importing code - features completed: leaderboards, statistics, my events, future events, event sign-up/drop, view event details, check-in/out, view org hours, add org hours, add new org
made methods non-static in all view models and updated the corresponding view classes
Fixed an issue where the SelectionChanged event would not fire on the Events Page for editing and viewing volunteer times.
Implemented the updateVolunteerTimes method in EventsModel. Removed EditTimesPage since it was a duplicate of EditVolunteerTimesPage.
Finished linking EditVolunteerTimesPage to its ViewModel so that the selected time is passed to the Model. Fixed error messages for event check-in/out. Cleaned up VolunteersPageViewModel code so that it is less repetitive.
Fixed an issue where the wrong page was passed in for navigating to EditVolunteerTimes. Replaced the MessageBoxControl with two separate ones because regular text and passwords require different UI controls. Fixed issues with NullReferenceExceptions in SignupPage.xaml.
Removed references to SelectedEvent and SelectedOrg. Completed IMPACT Sign up.
