enhancement: show class diagram in OMEdit

Basically a duplicate of this SO question:

When reading code with many levels of inheritance, it would be very helpful to see a class diagram, so that it is immediately clear what parameters, variables etc were added where.

Is such a functionality available already? Maybe using some script?
It would be nice to be able to just see such a diagram with a single click from OMEdit.

In a second step, the diagram could be interactive, e.g. allow to navigate to a class or similar.

I very strongly support this.

For some reason, this feature was never implemented in Dymola, though I think it would be extremely valuable to improve the understaning of libraries that use inheritance heavily, such as Modelica.Media and Modelica.Fluid.
