  Creates a form object from a user-specified configuration.
  
  # Example
  
  This example creates a <a href="ControlGroup-class.html"><code>ControlGroup</code></a> that consists of a `login` <a href="Control-class.html"><code>Control</code></a>, and a nested 
  <a href="ControlGroup-class.html"><code>ControlGroup</code></a> that defines a `password` and a `passwordConfirmation` <a href="Control-class.html"><code>Control</code></a>.
  
  ```
   var loginForm = builder.group({
     login: ["", Validators.required],
  
     passwordRetry: builder.group({
       password: ["", Validators.required],
       passwordConfirmation: ["", Validators.required]
     })
   });
