Merge remote-tracking branch 'origin' into progress_messages
Got the progress bar working.

I accomplished this outside of the ANSIControl class so it is a smaller amount of code to accomplish what I need.

This prints the progress on the screen and also prints a blank line at the end so the terminal prompt appears correctly on screen.
