Dui Tenga Uma mac Briuin - Dui Tenga Uma mac Brion and legendary ancestors

In the project of detaching and disentangling the mythological and legendary ancestors in the early tree, this line looks like it can get cut here -- Dui Tenga Uma appears to be historical; his father is more problematic.

I propose that we detach Dui Tenga Uma from his parents, providing notes and links to the legendary high kings he's attached to now.
