Requires jQuery Cookies plugin *  (https://github.com/carhartl/jquery-cookie) * - cookieParams: (default: {}) Object that allows customizing cookie *  parameters * - failStep: guiders property allows you to name a step to show if the *  show case fails (attachTo element is missing). For obvious reasons, this *  should not have an attachTo * - _buttonClass: property allows you to change the default button "classname" *  for all guider buttons (default: guider_button) * * - resume: start up tour from current place in ookie (if set). This is *  useful when your tour leaves the page you are on. Unlike show, it will *  skip steps that need to be skipped. * - endTour: Like hideAll but it remembers to remove the cookie position. * - initGuider: Allows for initializing Guiders without actually creating *  them (useful when guider is not in the DOM yet. Avoids error: *     * * - autoAdvance: property allows binding to an element (and event) to *   auto-advance the guider. This is a combination of onShow binding plus *   removing of bind when next is done. * - shouldSkip: property defines a function handler forces a skip of this step *   if function returns true. * - overlay "error": If not set to true, this defines the class of the overlay. *   (This is useful for coloring the background of the overlay red on error. * - onShow: If this returns a guider object, then it can shunt (skip) the rest *  of show * * @author tychay@php.net Patches for WordPress.com Guided Tour * @todo Merge in this https://github.com/jeff-optimizely/Guiders-JS/pull/33 and modify so it so it checks either visibility or DOM * @todo: add pulsing jquery.pulse https://github.com/jamespadolsey/jQuery-Plugins/tree/master/pulse/ * @see https://github.com/tychay/Guiders-JS */
