/**
* Assess a submission or view the single assessment
*
* Assessment id parameter must be passed. The script displays the submission and
* the assessment form. If the current user is the reviewer and the assessing is
* allowed, new assessment can be saved.
* If the assessing is not allowed (for example, the assessment period is over
* or the current user is eg a teacher), the assessment form is opened
* in a non-editable mode.
* The capability 'mod/workshop:peerassess' is intentionally not checked here.
* The user is considered as a reviewer if the corresponding assessment record
* has been prepared for him/her (during the allocation). So even a user without the
* peerassess capability (like a 'teacher', for example) can become a reviewer.
