The application consists of a set of tabs, each containing one or more panel stacks made up of one or more panels. For example, the Find tab is associated with two panel stacks: one to search for solutions and another to view solutions. Each of those panel stacks contains a set of panels that are rendered when that panel stack is loaded. Panel stacks and panels are defined in the ServiceSharedRepository as items of type DefaultPanelStack and DefaultPanel respectively.
