Training stage and work in progress Cleaning stage

The beta release contains a completed training stage and a work in progress cleaning stage. The reason why the cleaning stage is still a work in progress is because I still need some data to analyze before it can truly be declared completed. I also added some more functionality to the manager node, like progress bars and colored print statements. The nice thing about the progress bars is that by default they have a built-in timer that keeps track of how long certain processes take to complete. Very nice!

The next pre-release, gamma, will contain a working attack and clean stage and then hopefully jespipe will be ready to be released to the greater community!
