ScheduleClass Credential not found
When a new class is added, it is not found in a credential. This is because the credential was not linked to the new course. A new course is created when you ???. The courses are linked to credentials when you update the credential. Need to find out how new courses are added and how the YRTR is used for courses and credentials.

Really working on adding a new class and enable/disable Add button.

Add / Remove meetings does not have the correct add numbers. (ClassMeetingIndex starts at 1. Needs to -- when you remove meeting)
remove meeting also needs to Validate_ScheduleClass().
