/**
 * The basic tab list is displayed when Information, Warning or Error is the
 * selected element in the override tests view.
 * <p>
 * The OverrideTestsView TabbedPropertySheetPage example is a look at the
 * properties view after the migration of a TabFolder/TabItem framework to the
 * tabbed properties view. In the case of a TabFolder, the folder (provider)
 * knows both the tab labels and tab items. This aligns to the tabbed properties
 * view, but the tab labels are tab descriptors and tab items are section
 * descriptions. This does not work with the default framework as the tabs
 * provide the sections. In this case, the IOverridableTabListContentProvider
 * framework has been provided.
 * <p>
 * The overridable tab list is a content provider that provides both the
 * sections and the tab labels.
