Debug mode and comments added

Added 'run-debug' task to makefile to enable easy, local node-debug mode (replaced existing unused 'debug' task)
Corrected naming of 'methode' and 'fastft' controllers to being 'capi' and 'clamo' respectively
Inserted some documentation comments
Added TODO comments for other instances of 'method' and 'fastft' references that should probably be refactored in the future.
Ok, I'm going to keep the change to 'capi' in, as that's definitely more correct than 'methode'  to my mind (as methode is actually just a nightmarish piece of software used by editorial that I seriously hope none of us ever have to deal with - I have done in the past, it's hellish).

I'm going to change back fastft and cross my fingers that the info for this comes from capi in the future to remove issue :)
