    Veogen templates do the right thing. Don't worry about the missing
    constructor, do not added it, you will (and should) never call it
    directly.

    When creating a new DisplayBoard you'll see in the code for the
    tutorial that Janine uses:

            DisplayBoard displayBoard =
    (DisplayBoard)EOUtilities.createAndInsertInstance(session
    ().defaultEditingContext(), "DisplayBoard");

    This is such a common line of code that the Veogen templates generate
    factories that do that for you.

    So you can call:

            DisplayBoard displayBoard =
    DisplayBoard.newDisplayBoard(session().defaultEditingContext());
