Componentised doesn't have an inheritance strategy really, it's a convenient
way to *manage* inheritance strategies for things.

Loader should set up a common base class for the table classes that's
isa DBIx::C::DB and has the storage info set on it. This is pretty much
the same as what compose_connection from DBIx::C::Schema does (although
Schema does some extra magic to put the thing in its new namespace, of
course)
