"ST80" is the MVC UI framework, in the same sense that "Morphic" is the
Morphic UI framework. I'm sure that ST80 started out as a general category
of all the stuff that originated in ST80, but as a practical matter, nowadays
it refers to MVC. An MVC user interface is hosted in an MVCProject, just
as a Morphic user interface is hosted in a MorphicProject.
