extends PageComparator

Author:

lejafr This class implements comparision logic to compare first by a date element desc and than headline asc. This comparision logic fits perfect for a news list. The forceDescendingOrdering makes no sense here. All pages in the list needs to have this date element. Very often they are instances of the same template.
