org.eclipse.jface.action.IContributionManager
A contribution manager organizes contributions to such UI components as menus, toolbars and status lines.
A contribution manager keeps track of a list of contribution items. Each contribution item may has an optional identifier, which can be used to retrieve items from a manager, and for positioning items relative to each other. The list of contribution items can be subdivided into named groups using special contribution items that serve as group markers.

The IContributionManager interface provides general protocol for adding, removing, and retrieving contribution items. It also provides convenience methods that make it convenient to contribute actions. This interface should be implemented by all objects that wish to manage contributions.

There are several implementions of this interface in this package, including ones for menus ( {@link MenuManager MenuManager}), tool bars ( {@link ToolBarManager ToolBarManager}), and status lines ( {@link StatusLineManager StatusLineManager}).
