  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.
