Extension:GuidedTour/Shared tour instructions

Background and design

 * 1) Consult the design recommendations.
 * 2) Choose a tour name.
 * 3) For each step in your tour:
 * 4) Choose title and description text.
 * 5) Then, choose whether the step will have an attachment or a central overlay:
 * 6) * Attachment positions a step near a page element such as the Edit tab, a link, or the save button. You identify the page element using a selector.  Any jQuery selector can be used.  In general, this includes all CSS selectors.  This example positions near the Edit tab using an id selector:
 * For attachments, you must choose an attachment position. The choices are topLeft, top, topRight, rightTop, right, rightBottom, bottomRight, bottom, bottomLeft, leftBottom, left, leftTop.  You can experiment with these values, and may want to test in a skin beside your primary one (using the useskin parameter).
 * 1) * Overlay simply shows the step in the center of the screen. It allows you to explain something without attaching to an element.
 * 2) Choose the button actions.  If you want the user to click something (such as the edit tab), you can provide no explicit buttons (an Okay button that dismisses the step will still show).  Otherwise, you will want to specify one or more.  You can specify arbitrary button actions.  However, there are helpers included for common behaviors of the Okay button:
 * 3) *  - Will go the next step, unless the user checked the "End tour" checkbox.
 * 4) *  - Will end the tour
 * 5) By default, the step will close when they click outside it.  In some cases, such as on the edit page, you may want to disable this by including:
 * 6) Decide if you want automatic skip behavior.  In some cases, you will want to automatically skip a step based on the current state.  For example, if you have a step asking the user to click Edit, you will want to skip if they're already on the edit page:
 * 7) It is recommended to use debug mode while developing your tours.
