/**
 * A modal needs to be created only once per instance of wed. After creation it
 * must be installed into the DOM tree of the page on which it is going to be
 * used. The method [[Modal.getTopLevel]] must be used to get the top level DOM
 * element of the modal which will be inserted into the page. Once inserted, the
 * modal is ready to be used once, twice, or more times. It need not be removed,
 * re-created, etc. The method [[Modal.modal]] just needs to be called each time
 * the modal must be displayed.
 *
 * A typical usage scenario would be:
 *
 * <pre>
 *   // Modal setup.
 *   mymodal = new Modal();
 *   mymodal.setTitle("My modal");
 *   mymodal.setBody(...);
 *   mymodal.addYesNo();
 *   // This is a generic example of how to add the modal to a page.
 *   $("body").append(mymodal.getTopLevel());
 *
 *   ...
 *
 *   // Modal use
 *   mymodal.modal(function () {...});
 *   switch(mymodal.getClickedAsText()) {...}
 *
 *   ...
 *
 *   // A second use of the same modal
 *   mymodal.modal(function () {...});
 *   switch(mymodal.getClickedAsText()) {...}
 * </pre>
 *
 * If the same modal must be displayed on two different pages, then two Modal
 * objects should be created, one per page.
