title: How can I creat a sails.js project with coffee script and ES6
body: <p>I try to create sails.js project with coffee script and ES6
  First, I use sails new 'appName'
  and 
  npm install coffee-script --save 
  npm install babel --save</p>
  
  <p>and modify app.js </p>
  
  <pre><code>options = {
    loose     : "all",
    stage     : 1,
    ignore    : null,
    only      : null,
    extensions: null
  };
  require("sails-hook-babel/node_modules/babel/register")(options);
  </code></pre>
  
  <p>but it's something wrong </p>
  
  <p>I see others can create it by auto(It can creat app.coffee local.coffee...etc don't need to modify)
  How to do this?</p>
