## TODO

- [x] Create a `getCurrent` method to replace `getStep`
- [x] `ProgressBar::setCurrent` should auto-start the ProgressBar.
- [x] You should be able to pass `max` to `start`
- [x] `barCharOriginal` not needed. Logic can simply be part of `getBarChar`
- [x] `getStepWidth` is internal information that should not be public
- [x] when verbosity set to quiet, the progress bar does not even need to execute all the logic to generate output that is then thrown away
- [x] Allow to advance past max.
- [x] negative max needs to be validated
- [x] `getProgressPercent` should return float instead of int.
`$this->defaultBarChar` is not used anywhere else. Just put the value directly and remove the private property.
