A bit like groups; but for classes.
I'd like to be able to create a package that includes specific classes (or allow the customer to fill the package with allowable classes).
Enrolling in the package should enroll the dancer in each of the classes included in package, and not allow capacity for any 1 of the included classes to go over (ie, waitlist on the package)
The package would override tuition for the classes and have a set rate instead.
The classes in the package should still be available to others to enroll in, without doing the entire package.
Packages should have age requirements, and override the class age requirements.
