This is a basic implementation of the actual content generation in the workshop
generator. Note the we do not generate actual grading form data (which is what
the grading strategy plugins would do), just their results.
The availability restrictions that apply to user lists (group, grouping)
now apply in workshop:
* In user lists.
* When randomly allocating users (also now works as expected if you use
group mode and a grouping with the activity).
When different ID's are set for each sequence a number
of unit test failures appear. They have been corrected
to allow unit tests to pass with the new generator in place.
This event was missed in the previous workshop add_to_log change over. The
switch phase event has been moved into the workshop::switch_phase() method.
Also workshop::log() has been deprecated. Developers should use the event
classes to log events.
