Requirement: Deep linking
On launching through LTI, the user should be taken directly to the resource that has been specified for that activity. There should be no need for the student to navigate through the edX course in order to get to the correct assignment.
Implementing this requires that we can directly address edX content at the appropriate level of granularity. This is straightforward if we link to edX material at the section level, but may require more development work if we want to address a leaf xblock.
