[Building Sakai] proposal to deal with Gradebook / Lessons interaction

[Charles Hedrick]

Ugh. I was thinking of isExternalAssignmentVisible. Other approaches would be needed for the other methods. Still, I do believe it would be feasible to do it by this approach rather than actually modifying the Assignment and Samigo ExternalAssignmentProvider's. I'd be willing to do the code if people agreed on this approach.
