/**************
.UseImp<MyPages>()

or

.UseImp<MyPages>(ImpConfiguration
.NotFoundType<NotFoundPage>()
.RootPageNamespace("ConsoleTest.Pages")
.RootTemplateNamespace("ConsoleTest.Templates")
.CDNPrefix("cnd.domain.com")
);

Overloads to get strings with a delegate instead
Or a .FromConfiguration which takes an IImpConfiguration instance
NotFoundType could potentially be found by looking for attributes in assembly
- error out if more than one is found, or just use first one
Any way to avoid using a string for namespaces?
