Looks pretty good @eerhardt, thank you for working on this. My only real major comment is the naming, something shouldn't call itself a transformer factory unless it is a factory that makes transformers, and this definitely is not that. 😄 But aside from that, looks great, thank you.

Replace our MEF usage, which is only used by custom mapping transforms, with the ComponentCatalog class.

OK, @TomFinley, I've renamed the classes. Can you take a look?

@Ivanidzo4ka @yaeldekel - can I get a second pair of eyes?
