React to Courseware section changes #5
Description
When sections are added/deleted in Courseware, these should be added/deleted in LearningNet as well.
Changed/added Courseware sections should also trigger the recalculation of the respective cost values. Currently, all cost values are recalculated at once whenever the LearningNet settings are saved (which is inefficient and inconvenient).
This issue probably requires the integration of LearningNet into Courseware or at least some kind of observer-notification functionality in Courseware.
