// INSTRUCTIONS
// Create an relative or absolutely positioned container for the rotator/slideshow.
// Give that element the eRotator class and a unique id
// Place your element(s) of choice within the container
// Set the variables below to achieve a desired effect

// Set Animation slideshow and Element Type (img, p, *)

// Final States (after animation, completed state)
var finalTop = 0;

// Initial States (animate in, set to final if no animation)

var postTop = finalTop; // add ['-='+] or ['+='+] to slide
var postLeft = finalLeft; // add ['-='+] or ['+='+] to slide

// Set Animation Time and Interval
