Returns the key next key in a database traversal. The
following code prints every key in the database \code{db}, without
having to create a list in memory that contains them all:
\begin{verbatim}
k = db.first()
while k != None:
print k

Return the key that comes before \var{key} in a forward-traversal of
the database. In conjunction with \method{last()}, this may be used
to implement a reverse-order traversal.
