A simple command-line progress bar.

Usage:

>>> progress.update(4) #halfway, zero indexing

Reading data: [############### ] 50.0%

Multi-indices, from slowest to fastest:

>>> progress = ProgressBar('Reading data', 10, 10)

Reading data: [ ] Starting

>>> progress.update(9, 8)

Reading data: [############################# ] 99.0%

Reading data: [ ] Starting

>>> progress.update()

Reading data: [ ] 1.0%
