Intensional objects

We summarize the interaction between the theory behind intensional programming, as seen in Lucid; and intensional versioning, as seen in Lemur, Intensional HTML, ISE, VMAKE, etc. These two concepts can be seen to be duals of each other, and they rely on dual notions of store, the warehouse for caching values, and the catalog for providing definitions. Catalogs contain intensional objects, which are openable boxes labelled by Lucid contexts. Finally, Lucid contexts are now first-class values.
