/**
 * CMultiFileUpload generates a file input that can allow uploading multiple files at a time.
 *
 * This is based on the {@link http://www.fyneworks.com/jquery/multiple-file-upload/ jQuery Multi File Upload plugin}.
 * The uploaded file information can be accessed via $_FILES[widget-name], which gives an array of the uploaded
 * files. Note, you have to set the enclosing form's 'enctype' attribute to be 'multipart/form-data'.
 *
 * Example:
 * <pre>
 * <?php
 *   $this->widget('CMultiFileUpload', array(
 *      'model'=>$model,
 *      'attribute'=>'files',
 *      'accept'=>'jpg|gif',
 *      'options'=>array(
 *         'onFileSelect'=>'function(e, v, m){ alert("onFileSelect - "+v) }',
 *         'afterFileSelect'=>'function(e, v, m){ alert("afterFileSelect - "+v) }',
 *         'onFileAppend'=>'function(e, v, m){ alert("onFileAppend - "+v) }',
 *         'afterFileAppend'=>'function(e, v, m){ alert("afterFileAppend - "+v) }',
 *         'onFileRemove'=>'function(e, v, m){ alert("onFileRemove - "+v) }',
 *         'afterFileRemove'=>'function(e, v, m){ alert("afterFileRemove - "+v) }',
 *      ),
 *   ));
 * ?>
 * </pre>
