 * and Ferri Sutanto (https://gist.github.com/ghprod/0bb7f8d207ba7838a0e6)
 * Uses meta csrfToken and meta csrfParam based on: https://github.com/rails/jquery-ujs/blob/master/src/rails.js

 * Examples :
 * <a href="posts/2" data-method="delete">
 * - Or, request confirmation in the process -

 *
 * Uses CSRF token defined in your <head> tag. For Laravel 5, use the following code in a blade template :
 * <meta name="csrf-token" content="{{ csrf_token() }}">
