Work Type Inheritence

Use cases might dictate specialties of work types and imply the ability to share behaviors of closely related things. Currently you can generate a new work type in Hyrax, but ideally you should also be able to say it is 'a kind of' work type, thus allowing a hierarchy of inheritance. This is a page to collect some design thoughts on how that might work.
