* Refactored indexes: TBufIndex is now a class instead of a record. All index-related code (such as for scrolling) should eventually be placed into this class. This is not done yet completely, but a start is made. * From now on, FLastRecBuf.Next of the dl-list is linked to the first record. This way it is possible to move the cursur to the first record by setting the current record to the last record in the list. With this trick several corner-case checks which were necessary on every scroll-action on the dataset have become obsolete and are removed. ........ r11386 | joost | 2008-07-15 23:37:10 +0200 (Tue, 15 Jul 2008) | 1 line

* Created two sub-classes of TBufIndex: TDoubleLinkedBufIndex and TArrayBufIndex, so that it is now possible to decide at run-time which kind of buffer should be used. ........ r11492 | joost | 2008-07-31 00:03:37 +0200 (Thu, 31 Jul 2008) | 1 line
