  * Revision 1.5  2003/04/13 18:07:10  zecke

  * QString -> const QString&

  * Revision 1.4  2003/03/21 14:32:54  mickeyl
  * g++ compliance fix: default arguments belong into the declaration, but not the definition
  *
  * Revision 1.3  2003/03/21 12:26:28  eilers
  * Fixing small bug: If we search a birthday from today to today, it returned
  * every contact ..
  *
  * Revision 1.2  2003/03/21 10:33:09  eilers
  * Merged speed optimized xml backend for contacts to main.
  * Added QDateTime to querybyexample. For instance, it is now possible to get
  * all Birthdays/Anniversaries between two dates. This should be used
  * to show all birthdays in the datebook..
  * This change is sourcecode backward compatible but you have to upgrade
  * the binaries for today-addressbook.
  *
  * Revision 1.1.2.2  2003/02/11 12:17:28  eilers
  * Speed optimization. Removed the sequential search loops.
