Hearing no feedback, I studied the Aegis Configuration object further. I concluded that it is, in fact, a good modular container of the type creation options, with an unhelpful name.
So, next commit will rename it to TypeCreationOptions, preserving the old name as an @deprecated subclass. I've also been added javadoc. The Confluence doc will need work; I still wonder if we should fork all of confluence for 2.1 before we get more hopelessly confused pages containing mixtures of 2.0.x and 2.1 doc.
