The advice factory from the Microcontainer is sort of there in a "bodged" way.
It seems slow and think part of what is doing is probably redundant
and/or it is actually duplicating work.

Some of the complication comes from it initially being written
as a normal dependency, but it now also supports the "lazy" dependency.
So again this needs tidying up.

Additionally, I'd like the "use case" xml to be able to deploy
all the aop metadata, not just advices.
This is fairly low priority and doesn't need to be done for 2.0.0M1

I'm not even sure that much of this metadata would even benefit
from IOC configuration. The users would benefit from having a single
file in which to describe everything together.
i.e. introductions, pointcuts, advices, pojo services that the advices delegate to, etc.
