class CategoriesCheckBox(LabelFrame):
    ''' This class implement a widget for displaying and
        configuring categories.

        Attributes:
            parent (Tk object): widget parent.
            frame_with_boxes (Frame): frame for check buttons.
            canvas (StyledCanvas): canvas for all objects of this widget.
            options (dict of str to list of IntVar and int): dictionary
                that maps
                category name to two IntVar objects that keep track of the
                state of check buttons and grid row index.
                The first check button is used
                for checking if category is non-discretionary. The second
                check button is used for checking if category is weakly
                disposal.
            nb_entries (int): total number of categories.
            add_headers (bool): if set to True, the widget displays column
                headers, if set to False column headers are not
                displayed.
            category_objects (dict of list of Tk objects): dictionary that
                maps category name to a list with three elements. The first
                element is Label with category name, the remaining elements
                are Checkbuttons used for non-discretionary and weakly
                disposal categories.
            params (Parameters): parameters of the model.
            category_type (str): INPUT_CATEGORIES or OUTPUT_CATEGORIES,
                defines type of categories (input or output).

        Args:
            parent (Tk object): widget parent.
            label_text (str): text that will be displayed on top of this widget.
            add_headers (bool): if set to True, the widget displays column
                headers, if set to False column headers are not
                displayed.
            params (Parameters): parameters of the model.
            category_type (str): INPUT_CATEGORIES or OUTPUT_CATEGORIES,
                defines type of categories (input or output).
