On low level, standard grading strategies subplugins do not store
personal themselves. They make use of the grades storage provided by
the workshop itself. What they do contain though is the information
about how the assessment forms were defined. And they are also
responsible for correctly interpreting the values in the central grades
table.
Grading strategies fulfil the contract with the parent workshop module
by implementing the workshopform_provider interface. That gives them a
chance to export data about the assessment form to each of exported
assessment.
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).
