Web Xcel Demo: View Services in nRoute

ViewServices in nRoute are basically UI implemented functionality exposed as services for non-visual consumption - think a Status-Bar as IStatusInfo service. The underlying idea is separation of concerns, so that non-visual components like ViewModels don't have to take dependency on View-based controls or on platform specific contraptions. To demonstrate ViewServices I've put up a small demo called Web Xcel - it replicates the Office Web look and feel for a spreadsheet type application.
