// v1.0 - Initial release
// v1.1 - Added ability to pause the scrolling action (requires you to assign
//        the bar to a unique arbitrary variable).
//      - Added ability to specify an action to perform after a x amount of
//      - bar scrolls. This requires two added arguments.
// v1.2 - Added ability to hide/show each bar (requires you to assign the bar
//        to a unique arbitrary variable).

// var xyz = createBar(
// total_width,
// total_height,
// background_color,
// border_width,
// border_color,
// block_color,
// scroll_speed,
// block_count,
// scroll_count,
// action_to_perform_after_scrolled_n_times
