CInputWidget is the base class for widgets that collect user inputs.
CInputWidget declares properties common among input widgets. An input widget can be associated with a data model and an attribute, or a name and a value. If the former, the name and the value will be generated automatically. Child classes may use resolveNameID and hasModel.
