Bug 60714 Call Hierarchy: display search scope in view title
Call Hierarchy should display the current search scope in the view title, like the Search View does. E.g.: Members calling 'updateView()' - in Workspace Calls from 'updateView()' - in Working Set: my projects
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/callhierarchy/SearchScopeActionGroup.java
return 0;
	}
	
	private String getScopeDescription(IWorkingSet[] workingSets) {
		return CallHierarchyMessages.getFormattedString("WorkingSetScope", new String[] {SearchUtil.toString(workingSets)}); 
	}
	
	/**
	 * Determines whether the specified working sets correspond to the currently selected working sets.
	 * @param workingSets
	 * @return
	 */
	private boolean isSelectedWorkingSet(IWorkingSet[] workingSets) {
		if (fSelectedWorkingSetNames != null && fSelectedWorkingSetNames.length == workingSets.length) {
			Set workingSetNames= new HashSet(workingSets.length);
			for (int i = 0; i < workingSets.length; i++) {
				workingSetNames.add(workingSets[i].getName());
			}
			for (int i = 0; i < fSelectedWorkingSetNames.length; i++) {
				if (!workingSetNames.contains(fSelectedWorkingSetNames[i])) {
					return false;
				}
			}
			return true;
		}
		return false;
