Recovery of the following Changes:

        * Implement fast and full featured version of sorted() for addressbook
        * Implement generic queryByExample for all Addressboook backends. It allows incremental search.
        * Update of API Documentation

+	* Implement fast and full featured version of sorted() for addressbook
+	* Implement generic queryByExample for all Addressboook backends. It allows incremental search.
+	* Update of API Documentation
 2004-11-18  Holger Freyther  <freyther@handhelds.org>
 	* Every Access can give a set of Occurrences for a period or a datetime
 	* QueryByExample, Find, Sort can be generically accessed by OPimBase 
 	  pointer interface
 	* OPimBackendOccurrence gets split up to OPimOccurrences by 
 	  OPimTemplateBase
 	* Add safeCast to various OPimRecords
 	* Kill memleak in OPimTodo
 	* Add SortVector implementations for OPimTodo and OPimContact
 	
 2004-??-??	The Opie Team <opie@handhelds.org>
 	* Implemented some important modifications to allow to use OPimRecords as it is, without
 	  have to cast them. This makes it possible to write applications which handling pim
 	  data in a generic manner (see opimconvertion tool) (eilers)
