Parameters
----------
parent: QWidget (mandatory)
the parent widget
control_name: str (mandatory)
the name of the control we want to create
control_value: str (mandatory)
the default control value
trait: Tait (mandatory)
the trait associated to the control
label_class: Qt widget class (optional, default: None)
the label widget will be an instance of this class. Its constructor
will be called using 2 arguments: the label string and the parent
widget.

-------
out: 2-uplet
a two element tuple of the form (control widget: QLineEdit,
associated label: QLabel)

----------
attributed_process: Process instance
process with attributes to be displayed
enable_attr_from_filename: bool (optional)
if enabled, it will be possible to specify an input filename to

override_control_types: dict (optional)
if given, this is a "factory" dict assigning new controller editor
types to some traits types in the parameters controller.
separate_outputs: bool
if True, inputs and outputs (traits with output=True set) will
be separated into two boxes.
user_data: any type (optional)
optional user data that can be accessed by individual control
editors
userlevel: int
the current user level: some traits may be marked with a non-zero userlevel, and will only be visible if the ControllerWidget userlevel is more than (or equal) the trait level.
scroll: bool
if True, the widget includes scrollbars in the parameters and
attributes sections when needed, otherwise it will be a fixed size
