Bind

The context class this View is a shape over — the type of the instance each Projection (or, for a visual subclass, each Band) is computed against. A reference to the Class entity itself, resolved through the import closure, so the validator can check that every path is reachable from this class. Required for a STANDALONE / addressable View (one named as a ViewPackage `rootView`, or run as a query): with no bound class it has no context to project from. OPTIONAL when the binding is supplied CONTEXTUALLY — a `look.View` attached to a class via `derivation.look` takes that class as its context, so authoring `bind` on it would be redundant with the attachment. Such an attached view MAY still name `bind` explicitly to be self-contained and addressable, but is not required to.
