\brief This is the facade for the abstract model data.
 All write access is running through this interface

The Model is the central place to access a qml files data (see e.g. rootNode() ) and meta data (see metaInfo() ).

Components that want to be informed about changes in the model can register a subclass of AbstractView via attachView().

\see QmlDesigner::ModelNode, QmlDesigner::AbstractProperty, QmlDesigner::AbstractView
