2 *	jquery.suggest 1.1b - 2007-08-06
3 * Patched by Mark Jaquith with Alexander Dick's "multiple items" patch to allow for auto-suggesting of more than one tag before submitting
4 * See: http://www.vulgarisoip.com/2007/06/29/jquerysuggest-an-alternative-jquery-based-autocomplete-library/#comment-7228
5 *
6 *	Uses code and techniques from following libraries:
7 *	1. http://www.dyve.net/jquery/?autocomplete
8 *	2. http://dev.jquery.com/browser/trunk/plugins/interface/iautocompleter.js
9 *
10 *	All the new stuff written by Peter Vulgaris (www.vulgarisoip.com)
11 *	Feel free to do whatever you want with this file
