+/**
+ * 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:
+ *
+ * Class by Stickman -- http://www.the-stickman.com
+ * with thanks to:
+ * [for Safari fixes]
+ * Luis Torrefranca -- http://www.law.pitt.edu
+ * and
+ * Shawn Parker & John Pennypacker -- http://www.fuzzycoconut.com
+ * [for duplicate name bug]
