FileHistory
wxFileHistory encapsulates functionality to record the last few files
visited, and to allow the user to quickly load these files using the
list appended to a menu, such as the File menu.
Note that this inclusion is not automatic; as illustrated in this example,
you must add files (and remove them) as deemed necessary within the framework
of your program.
Note also the additional cleanup required for this class, namely trapping the
enclosing window's Destroy event and deleting the file history control and its
associated menu.
