type: String

A string indicating which easing function to use for the transition.
The only easing implementations in the jQuery library are the default, called swing, and one that progresses at a constant pace, called linear. More easing functions are available with the use of the jQuery Easing Plugin.
Example:
var myEvoSlider = $("#mySlider").evoSlider({
easing: "swing"
});
