//
// Note: This plugin is UMD compatible, you can use it in node, amd and vanilla js envs

// Vanilla JS:
// <script src="underscore.js"></script>

// <script src="backbone.utils.js"></script>
//
// Node:
// var _ = require('underscore');
// var Backbone = require('backbone');
// var Utils = require('backbone.utils');
// 
//
// AMD:
// define(['underscore', 'backbone', 'backbone.utils'], function (_, Backbone, Utils) {
//    // do stuff with utils
// });
