Two thoughts on this section:

* I think it's a little confusing to jump right into a discussion about transferring nested constants before introducing the fact that you can use `as_stubbed_const`.
* The `:transfer_nested_constants` option comes straight from `stub_const`, which is already documented elsewhere:

https://relishapp.com/rspec/rspec-mocks/v/2-14/docs/mutating-constants

...so maybe this section can be shorter and just link to the `stub_const` docs?

BTW, @mattwynne -- do you have a recommendation for how to go about linking between different pages of the relish docs?  It's not totally clear to me what the URL for an individual file will be.  Does relish do some pre-processing along with the markdown that can convert some kind of page identifier to a link or something (e.g. like how github's wiki does it)?
