Title: Swapping CR for NL character in decisiontree.rb

The presence of this character doesn't cause any errors, just an annoying warning when using this gem with ruby 2: warning: encountered \r in middle of line, treated as a mere "space".

I'm guessing it's either from an old Mac or a corrupted Windows crlf; in any case, no other files in this repo seem to have this issue.
