Wraps a DateTimeRangeTrackBar for use in the .
This wrapper implements IDynamicFilterRangeTrackBar, which allows DynamicFilterDialog to communicate with the and other track bar controls in a simple and consistent manner.

The main task of this wrapper is to convert the Decimal range values used by the DynamicFilterDialog to and from the DateTime values used by the DateTimeRangeTrackBar control.
