  19  * Assess a submission or view the single assessment
  20  *
  21  * Assessment id parameter must be passed. The script displays the submission and
  22  * the assessment form. If the current user is the reviewer and the assessing is
  23  * allowed, new assessment can be saved.
  24  * If the assessing is not allowed (for example, the assessment period is over
  25  * or the current user is eg a teacher), the assessment form is opened
  26  * in a non-editable mode.
  27  * The capability 'mod/workshop:peerassess' is intentionally not checked here.
  28  * The user is considered as a reviewer if the corresponding assessment record
  29  * has been prepared for him/her (during the allocation). So even a user without the
  30  * peerassess capability (like a 'teacher', for example) can become a reviewer.
