+*  Post filter interface for Content Listing Framework.
+*  With this interface client you can add own post filter to
+*  exclude items from list model.<br><br>
+*  Example:
+*  @code
+*  // This example filters items by drive letter:
+*  // Items that are in phone memory are included to the list model.
+*  // All other items will be filtered.
+*  void CMyFilter::FilterItemsL( const TArray<MCLFItem*>& aItemList,
+*                                RPointerArray<MCLFItem>& aFilteredItemList )
+*      {
+*      TCharF phoneMemory( PathInfo::PhoneMemoryRootPath()[0] );
+*      TInt count( aItemList.Count() );
+*      for( TInt i = 0 ; i < count ; ++i )
+*          {
+*          TPtrC ptr;
+*          MCLFItem* item = aItemList[i];
+*          TInt error( item->GetField( ECLFFieldIdDrive, ptr ) );
+*          if( error == KErrNone )
+*              {
+*              TCharF memory( ptr[0] );
+*              if( memory == phoneMemory )
+*                  {
+*                  aFilteredItemList.AppendL( item );
