title: TypeScript with system.js module running in node error
body: <p>I would like to use the system.js module manager with TypeScript.
  My plan is to run typescript in node</p>
  
  <p>The problem is that, if i mark my Main.js (generated from Main.ts) file as the entry point, it will crash with this error:</p>
  
  <p>ReferenceError: System is not defined</p>
  
  <p>And it's normal, because my generated code start like this:
  System.register(["./Apple"], function(exports_1) {</p>
  
  <p>And for sure, there is no System class in node by default.
  So how to make typescript or node to load the system.js module?</p>
  
  <p>I can create an extra js file to load it with require, but i'm looking for a native solution inside typescript</p>
  
  <p>Thanks!</p>
