.. the OverviewWindow class has been refactored to extract out the core dashboard UX/UI into a new class ChartSpace. .. additionally, a ChartSpace contains a set of ChartSpaceItem which need to be subclassed by the developer. .. for the Overview a set of OverwiewItem classes have been introduced such as RPEOverviewItem, MetricOverviewItem and so on. These are subclasses of the ChartSpaceItem. .. The overview window implementation is now mostly configuration and assembly of a dashboard using OverviewItems and the ChartSpace. .. This refactor is to enable the ChartSpace to be used as a drop in replacement for the existing TabView. .. There are no functional enhancements in this commit, but the overview chart shouls appear to be unchanged by the user.
