Broken Link: CL-Async Threading -> Futures

[tamborello]

In the CL-Async Threading documentation, http://orthecreedence.github.io/cl-async/threading in the futures example, where it states, "Let’s integrate what we just did with futures," "futures" is a link to http://orthecreedence.github.io/cl-async/futures

Following that link results in a 404 error. However, there is a Github-hosted Futures project at: http://orthecreedence.github.io/cl-async/future
