014 * This reports lists all the requested courses and their properties.<br>
015 * <br>
016 * Namely:<ul>
017 * <li><b>Alternative</b> is 1 when the course was requested as an alternative (<b>Primary</b> is 0 or <b>Alternativity</b> is above 0)</li>
018 * <li><b>Enrolled</b> is 1 when the student is enrolled in the course</li>
019 * <li><b>Primary</b> is 1 when the request is from the Course Requests table, 0 when it is from the Alternate Course Requests table</li>
020 * <li><b>Priority</b> is the request's priority</li>
021 * <li><b>Alternativity</b> is the request's alternativity (0 for the primary course, 1 for the first alternative, 2 for the second alternative, etc.)</li>
022 * </ul>
