2598	New Model classes often break session saving	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Darwin-19.0.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-11-20)
Description
Whenever code creates a new Model subclass it breaks session saving unless it explicitly adds session saving support.  An example is the Pick Blobs tool outline box, reported in ticket #2596.

While it would be nice if tool writers always diligently added support for session saving, that is not likely to happen.  And having all session save broken by one model is really poor behavior.  So I think we should try to make Model subclasses either not save in sessions, or automatically save the geometry and maybe restore as a plain Model, rather than the subclass.
