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/SearchScopeProjectAction.java
super(group, CallHierarchyMessages.getString("SearchScopeActionGroup.project.text")); 
		this.fGroup = group;
		setToolTipText(CallHierarchyMessages.getString("SearchScopeActionGroup.project.tooltip")); 
		WorkbenchHelp.setHelp(this, IJavaHelpContextIds.CALL_HIERARCHY_SEARCH_SCOPE_ACTION);
	}
	
	public IJavaSearchScope getSearchScope() {
		IMethod method = this.fGroup.getView().getMethod();
		IJavaProject project = null;
		
		if (method != null) {
			project = method.getJavaProject();
		}
		
		if (project != null) {
			return SearchEngine.createJavaSearchScope(new IJavaElement[] { project },
					false);
		} else {
			return null;
		}
	}
