#5 Support additional majors

[N Napier]

The program currently only supports different concentrations in the business program. This limits its usefulness to instructors in other programs, or instructors that teach classes that have students from a variety of different programs. Need to change the program and associated documentation to allow multiple majors. Ideally, the list of acceptable majors would be configurable so that code changes would not be required as new majors and concentrations are defined.
