<h3>FileHistory</h3>

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.

<p>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. 

<p>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.
