title: Using $set() to add a User object to /users in Firebase
body: <p>I'm currently trying to add new users to Firebase via the AngularFire <code>$set()</code> method. I'm creating new users via the <code>$createUser</code> method from AngularFire. My code looks like this:</p>
  
  <pre><code>$scope.createUser = function() {
        $scope.auth.$createUser('dolly@gmail.com', 'password').then(function(user, err) {
          if (err) {
            console.log('ERROR: ' + err);
          } else {
            sync.$set('users', user);
          }
        });
  }
  </code></pre>
  
  <p>This is a creating new user and placing the new user object inside of users:{..}, however, it is also adding an additional user child object thats just duplicate data -- this is what the code is adding to Firebase:</p>
  
  <pre><code>{
  "users": {
      "email": "dolly@gmail.com",
      "id": "11",
      "isTemporaryPassword": false,
      "md5_hash": "xxxxxxxxxxxxxxx",
      "provider": "password",
      "sessionKey": "xxxxxxxxxxxxx",
      "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE0MDc5NDQ2NDYsInYiOjAsImQiOnsicHJvdmlkZXIiOiJwYXNzd29yZCIsImlkIjoiMTEiLCJ1aWQiOiJzaW1wbGVsb2dpbjoxMSIsImVtYWlsIjoiZG9sbHlAZ21haWwuY29tIiwibWQ1X2hhc2giOiIzsdrggfeedsaadrfcDc0ZDRhMTU5NTk2NzI1NzFmMDk2ZTZlNyIsImlzVGVtcG9yYXJ5UGFzc3dvcmQiOmZhbHNlLCJzZXNzaW9uS2V5IjoiM2MwMDNjODkxMDEzOWE5MjhlZTZjNWI1NjU5ZTRiZjMifSwiaWF0IjoxNDA3ODU4MjQ2fQ.p7-9GDtaNpBn1ICTLIUSwlPytaUGi-jyBgcO-LKHUys",
      "uid": "simplelogin:11",
      "user": {
      "email": "dolly@gmail.com",
      "id": "11",
      "isTemporaryPassword": false,
      "md5_hash": "xxxxxxxxxxxxxxx",
      "provider": "dfrggrssxxxxxxx",
      "sessionKey": "xxxxxxxxxxxxxxx",
      "uid": "simplelogin:11"
      }
  }
  </code></pre>
  
  <p>I ideally want my users object to look like the example in firebase, except with each user key to be whatever is inside <code>user.uid</code></p>
  
  <pre><code>users: {
      user1: {
        name: "Alice"
      },
      user2: {
        name: "Bob"
      }
  }
  </code></pre>
  
  <p>Where each new user will be added to the <code>users: {...}</code> key without the duplicate user child tacked on?</p>
