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 1.8  2003/02/21 16:52:49  zecke
  * -Remove old Todo classes they're deprecated and today I already using the
  * new API
  * -Guard against self assignment in OTodo
  * -Add test apps for OPIM
  * -Opiefied Event classes
  * -Added TimeZone handling and pinning of TimeZones to OEvent
  * -Adjust ORecur and the widget to better timezone behaviour
  *
  * Revision 1.7  2003/02/16 22:25:46  zecke
  * 0000276 Fix for that bug.. or better temp workaround
  * A Preferred Number is HOME|VOICE
  * A CellPhone is HOME|VOICE|CELL the type & HOME|VOICE test
  * triggers both
  * and the cell phone number overrides the other entries..
  *
  * as a temp I check that it's not equal to HOME|VOICE|CELL before setting the
  * number
  *
  * The right and final fix would be to reorder the if statement to make it
  * if else based and the less common thing put to the bottom
  *
  * OTodoAccessVcal fix the date for beaming

  * History:
  * $Log$
+ * 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.
+ *
+ * Revision 1.1.2.1  2003/02/10 15:31:38  eilers
+ * Writing offsets to debug output..
+ *
  * Revision 1.1  2003/02/09 15:05:01  eilers

  * Bugfix for calculating data diffs..
  *
  * Revision 1.10  2003/01/02 14:27:12  eilers
  * Improved query by example: Search by date is possible.. First step
  * for a today plugin for birthdays..
  *
  * Revision 1.9  2002/12/08 12:48:57  eilers
  * Moved journal-enum from ocontact into i the xml-backend..
  *
  * Revision 1.8  2002/11/14 17:04:24  eilers
  * Sorting will now work if fullname is identical on some entries
  *
  * Revision 1.7  2002/11/13 15:02:46  eilers
  * Small Bug in sorted fixed
  *
  * Revision 1.6  2002/11/13 14:14:51  eilers
  * Added sorted for Contacts..
  *
  * Revision 1.5  2002/11/01 15:10:42  eilers
  * Added regExp-search in database for all fields in a contact.
  *
  * Revision 1.4  2002/10/16 10:52:40  eilers
  * Added some docu to the interface and now using the cache infrastucture by zecke.. :)
  *
  * Revision 1.3  2002/10/14 16:21:54  eilers
  * Some minor interface updates
  *
  * Revision 1.2  2002/10/07 17:34:24  eilers
  * added OBackendFactory for advanced backend access
  *
  * Revision 1.1  2002/09/27 17:11:44  eilers
  * Added API for accessing the Contact-Database ! It is compiling, but
  * please do not expect that anything is working !
  * I will debug that stuff in the next time ..
  * Please read README_COMPILE for compiling !

  * History:
  * $Log$
+ * Revision 1.13  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 1.12.2.2  2003/02/11 12:17:28  eilers
+ * Speed optimization. Removed the sequential search loops.
+ *
+ * Revision 1.12.2.1  2003/02/09 15:05:01  eilers
+ * Nothing happened.. Just some cleanup before I will start..
+ *
  * Revision 1.12  2003/01/03 16:58:03  eilers
  * Reenable debug output
  *
  * Revision 1.11  2003/01/03 12:31:28  eilers
  * Bugfix for calculating data diffs..
  *
  * Revision 1.10  2003/01/02 14:27:12  eilers
  * Improved query by example: Search by date is possible.. First step
  * for a today plugin for birthdays..
  *
  * Revision 1.9  2002/12/08 12:48:57  eilers
  * Moved journal-enum from ocontact into i the xml-backend..
  *
  * Revision 1.8  2002/11/14 17:04:24  eilers
  * Sorting will now work if fullname is identical on some entries
  *
  * Revision 1.7  2002/11/13 15:02:46  eilers
  * Small Bug in sorted fixed
  *
  * Revision 1.6  2002/11/13 14:14:51  eilers
  * Added sorted for Contacts..
  *
  * Revision 1.5  2002/11/01 15:10:42  eilers
  * Added regExp-search in database for all fields in a contact.
  *
  * Revision 1.4  2002/10/16 10:52:40  eilers
  * Added some docu to the interface and now using the cache infrastucture by zecke.. :)
  *
  * Revision 1.3  2002/10/14 16:21:54  eilers
  * Some minor interface updates
  *
  * Revision 1.2  2002/10/07 17:34:24  eilers
  * added OBackendFactory for advanced backend access
  *
  * Revision 1.1  2002/09/27 17:11:44  eilers
  * Added API for accessing the Contact-Database ! It is compiling, but
  * please do not expect that anything is working !
  * I will debug that stuff in the next time ..
  * Please read README_COMPILE for compiling !

  *
  * =====================================================================
  * Version: $Id$
  * =====================================================================
  * History:
  * $Log$
+ * Revision 1.9  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 1.8  2003/02/21 16:52:49  zecke
  * -Remove old Todo classes they're deprecated and today I already using the
  * new API
  * -Guard against self assignment in OTodo
  * -Add test apps for OPIM
  * -Opiefied Event classes
  * -Added TimeZone handling and pinning of TimeZones to OEvent
  * -Adjust ORecur and the widget to better timezone behaviour
  *
  * Revision 1.7  2003/02/16 22:25:46  zecke
  * 0000276 Fix for that bug.. or better temp workaround
  * A Preferred Number is HOME|VOICE
  * A CellPhone is HOME|VOICE|CELL the type & HOME|VOICE test
  * triggers both
  * and the cell phone number overrides the other entries..
  *
  * as a temp I check that it's not equal to HOME|VOICE|CELL before setting the
  * number
  *
  * The right and final fix would be to reorder the if statement to make it
  * if else based and the less common thing put to the bottom
  *
  * OTodoAccessVcal fix the date for beaming
  *
  * Revision 1.6  2003/01/13 15:49:31  eilers
  * Fixing crash when businesscard.vcf is missing..
  *
  * Revision 1.5  2002/12/07 13:26:22  eilers
  * Fixing bug in storing anniversary..
  *
  * Revision 1.4  2002/11/13 14:14:51  eilers
  * Added sorted for Contacts..
  *
  * Revision 1.3  2002/11/11 16:41:09  kergoth
  * no default arguments in implementation
  *
  * Revision 1.2  2002/11/10 15:41:53  eilers
  * Bugfixes..
  *
  * Revision 1.1  2002/11/09 14:34:52  eilers

  * History:
  * $Log$
+ * Revision 1.13  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 1.12.2.2  2003/02/11 12:17:28  eilers
+ * Speed optimization. Removed the sequential search loops.
+ *
+ * Revision 1.12.2.1  2003/02/09 15:05:01  eilers
+ * Nothing happened.. Just some cleanup before I will start..
+ *
  * Revision 1.12  2003/01/03 16:58:03  eilers
  * Reenable debug output
  *
  * Revision 1.11  2003/01/03 12:31:28  eilers
  * Bugfix for calculating data diffs..
  *
  * Revision 1.10  2003/01/02 14:27:12  eilers
  * Improved query by example: Search by date is possible.. First step
  * for a today plugin for birthdays..
  *
  * Revision 1.9  2002/12/08 12:48:57  eilers
  * Moved journal-enum from ocontact into i the xml-backend..
  *
  * Revision 1.8  2002/11/14 17:04:24  eilers
  * Sorting will now work if fullname is identical on some entries
  *
  * Revision 1.7  2002/11/13 15:02:46  eilers
