i named the iterator basic_directory_iterator <CharT> and placed a
typedef basic_directory_iterator <char> directory_iterator behind it.

this function would imply current_directory (). if you call absolute
("") you should get the current directory but you cannot set it. i would
prefer supporting either both or none.

ps: i changed the code so that the directory_iterator changes an
empty string to "." in its ctor.
