title: Extend one module from angular app in a sub app
body: <p>I am developing a big angular application.
  The basic application contains only login form and principal menu.
  I would like to implement 2 plugins/modules to extend functionality of the main application.
  If I include Plugin1, I see a new item in menu and navigating from it I can see all Plugin1's views. Same thing with Plugin2 and other plugins..
  Another thing.. Plugin enabled/disabled have to depend from a configuration in json.</p>
  
  <p>How can I develop this functionality?</p>
  
  <p>Thanks</p>
