  6. I am the abstract superclass of all models of Helios.
  7. I am the "Model" part of the MVC pattern implementation in Helios.
  8. I provide access to an `Environment` object and both a local (model-specific) and global (system-specific) announcer.
  9. The `#withChangesDo:` method is handy for performing model changes ensuring that all widgets are aware of the change and can prevent it from happening.
  10. Modifications of the system should be done via commands (see `HLCommand` and subclasses).!

  51. I am a model specific to package and class manipulation. All browsers should either use me or a subclass as their model.
  52. I provide methods for package, class, protocol and method manipulation and access, forwarding to my environment.
  53. I also handle compilation of classes and methods as well as compilation and parsing errors.!

  417. I am the abstract superclass of all Helios widgets.
  418. I provide common methods, additional behavior to widgets useful for Helios, like dialog creation, command execution and tab creation.
  419. ## API
  420. 1. Rendering
  421. Instead of overriding `#renderOn:` as with other Widget subclasses, my subclasses should override `#renderContentOn:`.
  422. 2. Refreshing
  423. To re-render a widget, use `#refresh`.
  424. 3. Key bindings registration and tabs
  425. When displayed as a tab, the widget has a chance to register keybindings with the `#registerBindingsOn:` hook method.
  426. 4. Unregistration
  427. When a widget has subscribed to announcements or other actions that need to be cleared when closing the tab, the hook method `#unregister` will be called by helios.
  428. 5. Tabs
  429. To enable a widget class to be open as a tab, override the class-side `#canBeOpenAsTab` method to answer `true`. `#tabClass` and `#tabPriority` can be overridden too to respectively change the css class of the tab and the order of tabs in the main menu.
  430. 6. Command execution
  431. An helios command (instance of `HLCommand` or one of its subclass) can be executed with `#execute:`.!
