Realtime Customization

The following items can be set at any time. Changes cause an immediate bar refresh so no other action is needed:

• #progress_mark=: Sets the string used to represent progress along the bar.
• #remainder_mark=: Sets the string used to represent the empty part of the bar.
• #title=: Sets the string used to represent the items the bar is tracking (or I guess whatever else you want it to be).
• #format(format_string): If you need to adjust the format that the bar uses when rendering itself, just pass in a string in the same format.
