[ala-n]

CSS Carousel redererer:

Name: css

Principals:

• set state classes ('active', 'next', 'prev', 'pre-active')
• controls animation/transition competition
• uses only CSS classes to control carousel state (all stage/slide manipulation trough CSS)
• slide move support could be temporary skipped (ideally should work trough offset custom CSS variable)
