+     * The $animate service provides rudimentary DOM manipulation functions to insert, remove, move elements within
+     * the DOM as well as adding and removing classes. This service is the core service used by the ngAnimate $animator
+     * service which provides high-level animation hooks for CSS and JavaScript. 
+     *
+     * $animate is available in the AngularJS core, however, the ngAnimate module must be included to enable full out
+     * animation support. Otherwise, $animate will only perform simple DOM manipulation operations.
+     *
+     * To learn more about enabling animation support, click here to visit the {@link ngAnimate ngAnimate module page}
