title: Steroids with Parse back-end retrieve nested object
body: <p>I am developing an app with Supersonic and Parse as back-end. I have two classes with one to one relationship (imagine something like "course" and "teacher", with each course held by one teacher). 
  I am using the function of the supersonic.model find() to retrieve one course that include an attribute "teacher" which is the pointer to related record in the teacher class. How can I configure Parse in order to get all the information of the nested object (teacher in that case) directly when I call the find() function?
  So instead of having </p>
  
  <pre><code>{ "course": {
     "name" = "Math",
     "school" = 'London Business School",
     "teacher" = '3edrr3rf'
  }
  </code></pre>
  
  <p>having:</p>
  
  <pre><code>{ "course": {
     "name" = "Math"
     "school" = 'London Business School"
     "teacher": {
          "firstname" = "Sandra",
          "lastname" = "Jackson",
          "age" = "45"
     }
  }
  </code></pre>
  
  <p>Thanks,
  Damiano</p>
