Detailed Description

A ModelView class which represents the data in an AST.

If you are not familiar with the Qt Model-View interfaces see the Qt-documentation for QAbstractItemModel

The data are fetched from the AST on demand while the user browses through it so the model is build up on demand

There is a second tree build up (out of ModelNodes) which just holds the display-information but usually this display-tree is smaller than the whole AST because it's build up on demand
