/**

 * 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.
