jQueryプラグインを作るときのテンプレート。

jquery.plugin.js

(function($){
    var Plugin = function($t, settings){
        this.$el = $t;
        this.settings = settings;
        this.init();
    };

    Plugin.prototype = {
        init: function(){
          console.log("init", this, arguments);
        },
        standby: function(){
          console.log("standby", this, arguments);
        },
        start: function(){
          console.log("start", this, arguments);
        },
        stop: function(){
          console.log("stop", this, arguments);
        },
        reset: function(){
          console.log("reset", this, arguments);
        }
    };

    $.fn.plugin = function(options){
        if( typeof options == "string" ){
            var args = [];
            args.push.apply(args, arguments);
            return this.each( function(){
                var $t = $(this);
                var cls = $t.data("plugin");
                if(cls && cls[options]){
                    args.splice(0, 1);
                    cls[options](cls, args);
                }

        }else{
