EnrollmentSets and Enrollments

There is currently no way to get from an Enrollment to an EnrollmentSet in the CM API. The Sakai OOTB hibernate implementation has an EnrollmentSet object as a property to each Enrollment impl. As Josh has pointed out in emails before, this is a heavy memory object map. I proposed to Josh that he add a setter and getter for a String property for the EnrollmentSet's EID into the Enrollment interface. He said that he would look to add it for Sakai 2.5.
