/**
* Convert a single file-input element into a 'multiple' input list
* Usage:
*
* 1. Create a file input element (no name)
* eg. <input type="file" id="first_file_element">
*
* 2. Create a DIV for the output to be written to
* eg. <div id="files_list"></div>
*
* 3. Instantiate a MultiSelector object, passing in the DIV and an (optional) maximum number of files
* eg. var multi_selector = new MultiSelector( document.getElementById( 'files_list' ), 3 );
*
* 4. Add the first element
* eg. multi_selector.addElement( document.getElementById( 'first_file_element' ) );
*
* img_view boolean - 이미지 파일 첨부 미리보기
