// TODO: great functionality that breaks self-contained principles, grrr
// Re-map the dependency and activitylink information
// If a depency or activitylink has no mapping in the backup data then it could either be a duplication of a
// lesson, or a backup/restore of a single lesson. We have no way to determine which and whether this is the
// same site and/or course. Therefore we try and retrieve a mapping, but fallback to the original value if one
// was not found. We then test to see whether the value found is valid for the course being restored into.
