/**
 * This is the main endpoint which MoodleNet instances POST to.
 *
 * MoodleNet instances send the user agent to this endpoint via a form POST.
 * Then:
 * 1. The POSTed resource information is put in a session store for cross-request access.
 * 2. This page makes a GET request for admin/tool/moodlenet/index.php (the import confirmation page).
 * 3. Then, depending on whether the user is authenticated, the user will either:
 * - If not authenticated, they will be asked to login, after which they will see the confirmation page (leveraging $wantsurl).
 * - If authenticated, they will see the confirmation page immediately.
