"""# Deocrate class methods with magicgui
Demonstrates decorating a class method with magicgui.
Once the class is instantiated, `instance.method_name` will return a FunctionGui
in which the instance will always be provided as the first argument (i.e. "self") when
the FunctionGui or method is called.
