* autocomplete.js 1.1.0

*
* This Software shall be used for doing good things, not bad things.
* - Lorenzo Puccetti
*
* This is a simple autocomple library.
* The autocomple.js supports dynamic suggestions and history browsing.
* To set up autocomplete just use jQuery $('#div').autocomplete({ options: ["apple", "bannana", "strawberry", "pineapple"] })
*
* You can easily manipulate the suggestions list and history directly:
*
* var ac = $('#div').autocomplete({ options: ["apple", "bannana", "strawberry", "pineapple"] });
* ac.options = ["nope"]; //override suggestions list
* ac.historyInput = []; //clear history
* ac.options = [ {name:"option", "description":"description of the option", html: true} ] //Advanced suggestions (with descriptions)
*
