    This function is similar to what is provided by the ``fnmatch`` module in
    the Python standard library, but:
    
     * can match complete (relative or absolute) path names, and not just file
       names, and
     * also supports a convenience pattern ("**") to match files at any
       directory level.
    
    Examples:
    
    >>> pathmatch('**.py', 'bar.py')
    True
    >>> pathmatch('**.py', 'foo/bar/baz.py')
    True
    >>> pathmatch('**.py', 'templates/index.html')
    False
    
    >>> pathmatch('**/templates/*.html', 'templates/index.html')
    True
    >>> pathmatch('**/templates/*.html', 'templates/foo/bar.html')
    False
    
    :param pattern: the glob pattern
    :param filename: the path name of the file to match against
    :return: `True` if the path name matches the pattern, `False` otherwise
