Applied dimensionality

It's rather convenient to mark calculation-specific elements, which should be hidden from end-user, by placing some sign in front of dlist item name (for example '#').

Then in Contributor you can create saved selection "Auxiliary" with Filter "# *" to include all such elements. After that, create an Access-Table with "Auxiliary" Hidden, and there you go.

Add more '#' elements, and they'll become hidden automatically.
