+ * jquery.suggest 1.1b - 2007-08-06
+ * Patched by Mark Jaquith with Alexander Dick's "multiple items" patch to allow for auto-suggesting of more than one tag before submitting
+ * See: http://www.vulgarisoip.com/2007/06/29/jquerysuggest-an-alternative-jquery-based-autocomplete-library/#comment-7228
+ *
+ * Uses code and techniques from following libraries:

+ * 2. http://dev.jquery.com/browser/trunk/plugins/interface/iautocompleter.js
+ *
+ * All the new stuff written by Peter Vulgaris (www.vulgarisoip.com)
