* Move all public nested classes out into own files * Move more nested classes out * Tidy up and treat CA1034 as an error. Fix remaining nested classes. * Remove partial keyword from ThemeManager as it is no longer needed * Rename Bar to BarSeriesBar to more clearly indicate it is part of GraphView subsystem * Fix xmldoc references * Revert nesting changes to ConsoleDrivers * Change to file scoped namespaces and revert renames - LineCanvasCell back to just Cell - ApplicationRunState back to just RunState * Switch to file scoped namespaces
