Runtime
Runtime describes anything you can do to a module when it's running.
Runtime View
This is a view that appears in the Runtime tab of the run page.
To add a view to your module you make a new UserControl with WPF and then call SetRuntimeView() inside OnPreLoad. This takes in your UserControl as a type.
Your UserControl must have a constructor that contains your Module as the only argument.

Making a UserControl with WPF is outside the scope of this documentation.
