/**
* A workbench window is a top level window in a workbench. Visually, a
* workbench window has a menubar, a toolbar, a status bar, and a main area for
* displaying a single page consisting of a collection of views and editors.
*
* Each workbench window has a collection of 0 or more pages; the active page is
* the one that is being presented to the end user; at most one page is active
* in a window at a time.
*
*
* The workbench window supports a few {@link IServiceLocator services} by
* default. If these services are used to allocate resources, it is important to
* remember to clean up those resources after you are done with them. Otherwise,
* the resources will exist until the workbench window is closed. The supported
* services are:
*
*
* - {@link ICommandService}
* - {@link IContextService}
* - {@link IHandlerService}
* - {@link IBindingService}. Resources allocated through this service will
* not be cleaned up until the workbench shuts down.
*
*
* This interface is not intended to be implemented by clients.
