Menuitem class can be used to create a single menu item. As such menuitems
must always be embedded inside a <menu> tag which in turn is usually
embedded inside a <menubar> tag. See Menubar class for details.
Please note that the XML tag for menuitem class is just <item>
and not <menuitem> when creating menu items that are embedded
inside a <menu> tree. When creating isolated menu items that aren't
embedded inside a <menu> tree, you have to use <menuitem>,
though because otherwise RapaGUI wouldn't be able to know which class you are
referring to since <item> is used by many different classes.
If you do not specify a title for the menuitem, a separator item will be created. This is useful to group certain menuitems together which results in a more readable menu layout.
See Menubar class for an example.
