/**
 * SimpleModal is a lightweight jQuery plugin that provides a simple
 * interface to create a modal dialog.
 *
 * The goal of SimpleModal is to provide developers with a cross-browser 
 * overlay and container that will be populated with data provided to
 * SimpleModal.
 *
 * There are two ways to call SimpleModal:
 * 1) As a chained function on a jQuery object, like $('#myDiv').modal();.
 * This call would place the DOM object, #myDiv, inside a modal dialog.
 * Chaining requires a jQuery object. An optional options object can be
 * passed as a parameter.
 *
 * @example $('<div>my data</div>').modal({options});
 * @example $('#myDiv').modal({options});
 * @example jQueryObject.modal({options});
 *
 * 2) As a stand-alone function, like $.modal(data). The data parameter
 * is required and an optional options object can be passed as a second
 * parameter. This method provides more flexibility in the types of data 
 * that are allowed. The data could be a DOM object, a jQuery object, HTML
 * or a string.
 * 
 * @example $.modal('<div>my data</div>', {options});
 * @example $.modal('my data', {options});
 * @example $.modal($('#myDiv'), {options});
 * @example $.modal(jQueryObject, {options});
 * @example $.modal(document.getElementById('myDiv'), {options}); 
 * 
 * A SimpleModal call can contain multiple elements, but only one modal 
 * dialog can be created at a time. Which means that all of the matched
 * elements will be displayed within the modal container.
 * 
 * SimpleModal internally sets the CSS needed to display the modal dialog
 * properly in all browsers, yet provides the developer with the flexibility
 * to easily control the look and feel. The styling for SimpleModal can be 
 * done through external stylesheets, or through SimpleModal, using the
 * overlayCss and/or containerCss options.
 *
 * SimpleModal has been tested in the following browsers:
 * - IE 6, 7
 * - Firefox 2
 * - Opera 9
 * - Safari 3
 *
 * @name SimpleModal
 * @type jQuery
 * @requires jQuery v1.1.2
 * @cat Plugins/Windows and Overlays
