title: Granular access control with loopback
body: <p>I'm using the latest version of loopback and I'd like to work on the acl now. My app has a project model that should be available tontge team members, relative owner and admin. Of course I would like to have multiple projects with members that can be team member in multiple projects ... An owner could own multiple  projects and the admin should be able to see everything and to do everything. </p>
  
  <p>Loopback seem to have the possibility to define that. </p>
  
  <p>How would you approach that?</p>
  
  <p>Thanks</p>
