SIMS 7 - Attendance New changed marks APIs

With the intention of making the get changed attendance marks compatible with the other read and write calls, we are adding:

Session

private static List<DataClasses.SessionAttendanceExtended> SessionAttendanceReadTestPerson(DateTime lastUpdated)
{
    List<DataClasses.SessionAttendanceExtended> list = new List<DataClasses.SessionAttendanceExtended>();

    string SessionMarks = TPAR.GetXmlChangedSessionAttendancesV3(lastUpdated.AddMinutes(-20));
    XmlSerializer serializer = new XmlSerializer(typeof(DataClasses.SessionAttendancesExtended));
    using (StringReader reader = new StringReader(SessionMarks))
    {
        var test = (DataClasses.SessionAttendancesExtended)serializer.Deserialize(reader);
        list = test.SessionAttendanceExtended;
    }
    return list;
}

Lesson

private static List<DataClasses.LessonAttendanceExtended> LessonAttendanceReadTestPerson(DateTime lastUpdated)
{
    List<DataClasses.LessonAttendanceExtended> list = new List<DataClasses.LessonAttendanceExtended>();

    string LessonMarks = TPAR.GetXmlChangedLessonAttendancesV3(lastUpdated.AddMinutes(-20));
    XmlSerializer serializer = new XmlSerializer(typeof(DataClasses.LessonAttendancesExtended));
    using (StringReader reader = new StringReader(LessonMarks))
    {
        var test = (DataClasses.LessonAttendancesExtended)serializer.Deserialize(reader);
        list = test.LessonAttendanceExtended;
    }
    return list;
}

These will return <Lesson|Session>AttendanceExtendeds like their counterparts 

• GetXmlSessionAttendancesExtendedV3
• GetXmlLessonAttendancesExtendedV3

We recommend the use of these in place of the calls:

• TPAR.GetXmlChangedLessonAttendancesInRangeV3
• TPAR.GetXmlChangedSessionAttendancesInRangeV3

Because the formats of these are different to the rest of the calls.
