The discriminator for unions may be assumed to be integral, but need not be present within the union structure itself. Provide a way to obtain it from a layout element elsewhere in the buffer or by an oracle.

UnionDiscriminator: add capability
aef9f27 
Introduce new class hierarchy that supports the encode and decode
operations for a union discriminator.  Refactor the existing
prefix-layout approach for variant encoding to use this hierarchy.

Provides the basis of a solution to issue #7.
