This is the superclass for classes that cannot be instantiated.
There are a number of these in Tycho, mainly for "managers" of
things like colors and fonts. Inheriting from this class indicates
that such a class cannot be instantiated and places the classes neatly
into the Tycho class hierarchy. All the class contains is a constructor
that returns an error, thus preventing the class from being
instantiated.
Subclasses of this class thus are a collection of procs and common
variables.
It may be that this function would be better served by [incr Tcl]
namespaces -- this issue needs to be examined again when the
Tycho documentation system supports namespaces better.
