/**
This widget provides a standard menubar interface. Usually you will
put this widget along the top edge of your window. The height of the
widget should be 30 for the menu titles to draw correctly with the
default font.
The items on the bar and the menus they bring up are defined by a
single Fl_Menu_Item array.
Because a Fl_Menu_Item array defines a hierarchy, the
top level menu defines the items in the menubar, while the submenus
define the pull-down menus. Sub-sub menus and lower pop up to the right
of the submenus.

If there is an item in the top menu that is not a title of a
submenu, then it acts like a "button" in the menubar. Clicking on it
will pick it.
When the user clicks a menu item, value() is set to that item
and then:
- The item's callback is done if one has been set; the
Fl_Menu_Bar is passed as the Fl_Widget* argument,
along with any userdata configured for the callback.
- If the item does not have a callback, the Fl_Menu_Bar's callback
is done instead, along with any userdata configured for the callback.
The callback can determine which item was picked using
value(), mvalue(), item_pathname(), etc.
Submenus will also pop up in response to shortcuts indicated by
putting a '&' character in the name field of the menu item. If you put a
'&' character in a top-level "button" then the shortcut picks it. The
'&' character in submenus is ignored until the menu is popped up.
Typing the shortcut() of any of the menu items will cause
callbacks exactly the same as when you pick the item with the mouse.

/**
Creates a new Fl_Menu_Bar widget using the given position,
size, and label string. The default boxtype is FL_UP_BOX.
The constructor sets menu() to NULL. See
Fl_Menu_ for the methods to set or change the menu.
labelsize(), labelfont(), and labelcolor()
are used to control how the menubar items are drawn. They are
initialized from the Fl_Menu static variables, but you can
change them if desired.
label() is ignored unless you change align() to
put it outside the menubar.
The destructor removes the Fl_Menu_Bar widget and all of its
menu items.
