title: Passing form object by reference
body: <p>Hey! I've made a little boiler system that's controlled entirely by a form. The form components, however, call functions in a class for the boiler, radiators and so on.</p>
  
  <p>I've got a little main class to that instantiates all of the classes but I'm struggling to figure out how to pass the form object to those classes so that they can access the form's components.</p>
  
  <p>I guess I should be using mutator methods in each class to store the form object? How would I do this that's syntactically correct?</p>
  
  <p>Thank you! ;o)</p>
