hasInput()
See IWidget.hasInput.
Returns True if the submitted request form contains a value for the widget, otherwise returns False.
Some browser widgets may need to implement a more sophisticated test for input. E.g. checkbox values are not supplied in submitted forms when their value is 'off' -- in this case the widget will need to add a hidden element to signal its presence in the form.
