/**
* @module button
* @description <p>The Button Control enables the creation of rich, graphical 
* buttons that function like traditional HTML form buttons.  <em>Unlike</em> 
* traditional HTML form buttons, buttons created with the Button Control can have 
* a label that is different from its value.  With the inclusion of the optional 
* <a href="module_menu.html">Menu Control</a>, the Button Control can also be
* used to create menu buttons and split buttons, controls that are not 
* available natively in HTML.  The Button Control can also be thought of as a 
* way to create more visually engaging implementations of the browser's 
* default radio-button and check-box controls.</p>
* <p>The Button Control supports the following types:</p>
* <dl>
* <dt>push</dt>
* <dd>Basic push button that can execute a user-specified command when 
* pressed.</dd>
* <dt>link</dt>
* <dd>Navigates to a specified url when pressed.</dd>
* <dt>submit</dt>
* <dd>Submits the parent form when pressed.</dd>
* <dt>reset</dt>
* <dd>Resets the parent form when pressed.</dd>
* <dt>checkbox</dt>
* <dd>Maintains a "checked" state that can be toggled on and off.</dd>
* <dt>radio</dt>
* <dd>Maintains a "checked" state that can be toggled on and off.  Use with 
* the ButtonGroup class to create a set of controls that are mutually 
* exclusive; checking one button in the set will uncheck all others in 
* the group.</dd>
* <dt>menu</dt>
* <dd>When pressed will show/hide a menu.</dd>
* <dt>split</dt>
* <dd>Can execute a user-specified command or display a menu when pressed.</dd>
* </dl>
