Form data is now validated

When the user tries to add a class, the update activity now does some data validation. Also, if you wish to test the add class feature and you have already added classes from a previous build, you will need to delete the database first because I restructured it. To do this:
Go to android setttings.
Go to installed app list.
Find ggc-connect
Click on ggc-connect and there will be a button that says "clear data". Click on this. WARNING: This will delete ALL databases for the app (in case anyone else is using a database for their activities).

Also, now when you add a class, the list is updated.
