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.
I don't know enough about the background of this to be sure either way

@matthew-andrews - thoughts on this?
