        localStorage('key') //Returns the content if existing, or false if it doesnt
        localStorage('key', {
            content: the content, can be a raw object, string or raw array //it is stringified by the function
            local: true/false //yes or no if you want to store only in localStorage
        })
     */
    var localStorage = function(key, options) {
        if (options) { //store this data
            if (!options.local) {
                localStorage.setItem(key, JSON.stringify(options.content));
            } else { //also in cookie too
                if ($.cookie) $.cookie(key, options.content);
                localStorage.setItem(key, JSON.stringify(options.content));
            }
        } else if (options === false) { //if options == false
            localStorage.removeItem(key);
            if ($.cookie) $.cookie(key, false); //remove everything
        }

        //if only one argument is given retrieve that data from localstorage
        return arguments.length == 1 ? JSON.parse(localStorage.getItem(key)) : false;
    }
