/**
* Provides a basic modal window capability
*
* Use this directly (as described below) or copy and paste into your Process module's
* javascript file and modify as needed.
*
* USE
* ===
* 1. In your module call $this->modules->get('JqueryUI')->use('modal');
* 2. For the <a> link or <button> you want to open a modal window, give it the class
* "pw-modal". For a larger modal window, also add class "pw-modal-large". Other options
* are "pw-modal-small" and "pw-modal-full". Default is "pw-modal-medium".
* If using a <button> the "href" attribute will be pulled from a containing <a> element.
* If button not wrapped with an <a>, it may also be specified in a "data-href" attribute
* on the button.
*
*
* ATTRIBUTES
* ==========
* Other attributes you may specify with your a.pw-modal or button.pw-modal:
*
* data-buttons: If you want to use modal window buttons, specify a jQuery selector
* that identifies these buttons in the modal window. The original buttons will be
* hidden in the modal content and moved outside to the modal window interface.
*
* data-autoclose: If also using data-buttons, this option will make clicking any
* of those buttons automatically close the modal window, after the next page loads.
* This enables save actions to take place. You may also populate this property with
* a jQuery selector, in which case autoclose will only take place if the button
* matches the given selector.
*
* data-close: Populate with a selector that matches the button (or buttons) that
* should immediately close the window (no follow-up save or anything).
*
* MODAL CONTENT
* =============
* The window opened in the modal may optionally create a button or link with the
* class 'pw-modal-cancel'. When clicked, the window will immediately close. This
* can also be one of your 'data-buttons' if you want it to.
*
* EVENTS
* ======
* When the window is closed, the a.pw-modal link receives a "pw-modal-closed" event
* with the arguments (event, ui).
*
*
