Renamed softpipe directories and files to something less confusing.
softpipe/state_tracker --> state_tracker/ softpipe/ --> pipe/ softpipe/generic --> pipe/softpipe/ I don't think pipe is a great name, but I disliked all the others too. Luckily it's fairly easy to rename with git, so this can be revisited later.
