Provides CAD Exchanger data model.

The model encapsulates a scene graph (hierarchy of assemblies and parts) and is thus an entry point to entire 3D model data.

The model object can be and restored from a file in native CAD Exchanger format. Future versions may introduce model saving to CAD Exchanger native format.
