SignUpCallback

```
public interface SignUpCallback
```
A SignUpCallback is used to run code after signing up a ParseUser in a background thread.
The easiest way to use a SignUpCallback is through an anonymous inner class. Override the done function to specify what the callback should do after the save is complete. The done function will be run in the UI thread, while the signup happens in a background thread. This ensures that the UI does not freeze while the signup happens.
For example, this sample code signs up the object myUser and calls a different function depending on whether the signup succeeded or not.
```
 myUser.signUpInBackground(new SignUpCallback() {
   public void done(ParseException e) {
     if (e == null) {
       myUserSignedUpSuccessfully();
     } else {
       myUserSignUpDidNotSucceed();
     }
   }
 });
 
```
