Class Diagrams

[eluser]kimp[/eluser]
Hi,

I'm having difficulty visualising the class models that underpin CI. Does anyone have any examples? (I have seen these, thanks... http://ellislab.com/forums/viewthread/84490/)

A few issues:

- What's the CI object hierarchy look like?
- In general, should my application diagrams have a Controller class and a Model class only?
- What about Views?

Any assistance would be greatly appreciated.

Regards, Kim
