Removing now-false doc comments
Cleaning up literal-parsing regex code
Merge branch 'headless' of github.com:NetLogo/NetLogo into headless
Removing redundant casts
Correcting comment doc variable references
Avoiding '=' on methods of type 'Unit'
Avoiding unnecessary braces on single-item import
Removing unnecessary semicolons in Scala code
Removing unnecessary 'val' modifiers in case class
Removing all things I could find that were both private and unused

All one of them.  There are a ton of supposedly-unused variables, but the vast majority have public access, so... not really safe to remove them.
