I am the abstract superclass of all models of Helios.
I am the "Model" part of the MVC pattern implementation in Helios.

I provide access to an `Environment` object and both a local (model-specific) and global (system-specific) announcer.

The `#withChangesDo:` method is handy for performing model changes ensuring that all widgets are aware of the change and can prevent it from happening.

Modifications of the system should be done via commands (see `HLCommand` and subclasses).!

!HLToolModel commentStamp!
I am a model specific to package and class manipulation. All browsers should either use me or a subclass as their model.

I provide methods for package, class, protocol and method manipulation and access, forwarding to my environment.

I also handle compilation of classes and methods as well as compilation and parsing errors.!
