title: Meteor Collection undefined
body: <p>everyone.
  when I use a collection varibale in server folder, it makes a error."ReferenceError: Test is not defined"</p>
  
  <p>here is the file struct:
  collections
    --Test.coffee   #@Test = new Meteor.Collection "test"
  server
    --mock_data
      --test_server.coffee #console.log Test.find().count()   </p>
  
  <p>but if i use collection "test" directly in server fodler, it works.
  eg:
  server
    --test_server.coffee #console.log Test.find().count()   </p>
  
  <p>I think the file loading rule of Meteor should be responsible for this problem. But I still
  don't know why the problem occurred.</p>
