/**
 * Struct class to store the options of the ezcConsoleOutput class.
 * This class stores the options for the {@link ezcConsoleOutput} class.
 *
 * @property string $barChar
 *           The character to fill the bar with, during progress indication.
 * @property string $emptyChar
 *           The character to pre-fill the bar, before indicating progress.
 * @property string $formatString
 *           The format string to describe the complete progressbar.
 * @property string $fractionFormat
 *           Format to display the fraction value.
 * @property string $processChar
 *           The character for the end of the progress area (the arrow!).
 * @property int $redrawFrequency
 *           How often to redraw the progressbar (on every Xth call to advance()).
 * @property int $step
 *           How many steps to advance the progressbar on each call to advance().
 * @property int $width
 *           The width of the bar itself.
 * @property string $actFormat
 *           The format to display the actual value with.
 * @property string $maxFormat
 *           The format to display the actual value with.
 * @property int $minVerbosity
 *           Defines the minimum {ezcConsoleOutputOptions->$verbosityLevel}
 *           that is needed by the progress bar to be rendered. If
 *           $verbosityLevel is lower, the bar is skipped. Default is 0 to
 *           render always.
 * @property int $maxVerbosity
 *           Defines the maximum {ezcConsoleOutputOptions->$verbosityLevel} on
 *           which the progress bar is rendered. If $verbosityLevel is higher,
 *           the bar is skipped. Default is false, to render always.
