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/SearchScopeHierarchyAction.java
super(group, CallHierarchyMessages.getString("SearchScopeActionGroup.hierarchy.text")); 
		this.fGroup = group;
		setToolTipText(CallHierarchyMessages.getString("SearchScopeActionGroup.hierarchy.tooltip")); 
		WorkbenchHelp.setHelp(this, IJavaHelpContextIds.CALL_HIERARCHY_SEARCH_SCOPE_ACTION);
	}
	
	public IJavaSearchScope getSearchScope() {
		try {
			IMethod method = this.fGroup.getView().getMethod();
			
			if (method != null) {
				return SearchEngine.createHierarchyScope(method.getDeclaringType());
			} else {
				return null;
			}
		} catch (JavaModelException e) {
			JavaPlugin.log(e);
		}
		
		return null;
