This class is meant to be used with readline to provide Tab
    completion for users entering paths. The complete method can be
    passed to readline.set_completer directly, however, this function
    works best as a context manager. For example:

with Completer():
        raw_input()

In this example, Tab completion will be available during the call to
    raw_input above, however, readline will be restored to its previous
    state when exiting the body of the with statement.
