// Using the mixins looks like this:

// @include keyframes(move-the-object) {
//		0%   { left: 100px; }
//		100% { left: 200px; }
// }
//
// .object-to-animate {
//		@include animation('move-the-object .5s 1', 'move-the-object-again .5s 1 .5s');
// }

// Order from longest to shortest
// If anything changes edit here!!
