title: ng-repeat only objects with specific property value - custom filter?
body: <p>So say I have a JSON object 'user' with some basic properties like: 'name', 'address', 'role', etc.</p>
  
  <p>I want the ng-repeat to only spit out the objects in which the property 'role' equates to 'administrator'. How would I go about doing that?</p>
  
  <p>I'm thinking something like a custom filter, or possibly making a scope variable where I put the matching objects in an array, and then repeat through them. </p>
  
  <p>What is the best practice for this case? </p>
  
  <p>Thanks. </p>
