+/**
+ * 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' ) );
+ *
+ *   5. That's it.
+ *
+ *   You might (will) want to play around with the addListRow() method to make the output prettier.
+ *
+ *   You might also want to change the line 
+ *       element.name = 'file_' + this.count;
+ *   ...to a naming convention that makes more sense to you.
+ * 
+ * Licence:
+ *   Use this however/wherever you like, just don't blame me if it breaks anything.
+ *
+ * Credit:
+ *   If you're nice, you'll leave this bit:
