title: How to store UserID username in Titanium
body: <p>My app is similar to facebook. 
  I want to retain the userID/Username upon login screen, so that i could use it at rest of the application for queries online data.</p>
  
  <p>I tried storing it in a javascript object after successful login, but it gets washed away when i move to other screens.</p>
  
  <p>Thanks</p>
