function ensures that the specified class is a subclass of
and, rather than using insert_child to attach the widget to the parent's
children list, attaches the shell to the parent's pop-ups list directly.
A spring-loaded pop-up invoked from a translation table already must exist
at the time that the translation is invoked,
so the translation manager can find the shell by name.
Pop-ups invoked in other ways can be created ``on-the-fly'' when
the pop-up actually is needed.
This delayed creation of the shell is particularly useful when you pop up
an unspecified number of pop-ups.
You can look to see if an appropriate unused shell (that is, not
currently popped up) exists and create a new shell if needed.
