// mcbSlideShow - current version: 0.2
// Author: MOV
// The divs to be faded between should be absolutely positioned
// The container div should therefore be relatively positioned
// Image preloading is recommended - but is not currently supported by this script (although it might be later on).


// Changelog

// 0.2
// Implemented callback via setCallbackFinished

// 0.1
// Made first working version
