/**
* Modal renders a bootstrap modal on the page for its use on your application.
* Modal renders a modal window that can be toggled by clicking on a button.
*
* Basic usage:
* For example,
*
* ```php
* $this->widget(Modal::className(), array(
* 'id' => 'myModal',
* 'header' => 'Modal Heading',
* 'content' => '<p>One fine body...</p>',
* 'footer' => 'Modal Footer',
* // if we wish to display a modal button
* 'buttonOptions' => array(
* 'label' => 'Show Modal',
* 'class' => 'btn btn-primary'
* )
* ~~~php
* echo Modal::widget(array(
* 'header' => '<h2>Hello world</h2>',
* 'body' => 'Say hello...',
* 'toggleButton' => array(
* 'label' => 'click me',
* ),
* ));
* ```
* ~~~
*
* The following example will show the content enclosed between the [[begin()]]
* and [[end()]] calls within the modal window:
*
* ~~~php
* Modal::begin(array(
* 'header' => '<h2>Hello world</h2>',
* 'toggleButton' => array(
* 'label' => 'click me',
* ),
* ));
*
* echo 'Say hello...';
*
* Modal::end();
* ~~~
