  Defines a part of a form, of fixed length, that can contain other controls.
  
  A `ControlGroup` aggregates the values and errors of each <a href='Control-class.html'><code>Control</code></a> in the group. Thus, if
  one of the controls in a group is invalid, the entire group is invalid. Similarly, if a control
  changes its value, the entire group changes as well.
  
  `ControlGroup` is one of the three fundamental building blocks used to define forms in Angular,
  along with <a href='Control-class.html'><code>Control</code></a> and <a href='ControlArray-class.html'><code>ControlArray</code></a>. <a href='ControlArray-class.html'><code>ControlArray</code></a> can also contain other
  controls, but is of variable length.
