Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Done with examples. Made bar public.
Made self.bar public instead of "private". People who wish to have color progress bars (or change any of the bar's characters) may be more common. No point in leaving it private.
