[boost] [filesystem] recursive iteration

Hi Beman,

I just had a look at boost::filesystem, and it felt really good to use.
There is one common idiom that might be worth including: recursive
traversal.

So I would like some like

recursive_directory_iterator i( path( "foo" ) ) , end;
for( i.set_traversal_mode( files_only ); i != end; ++ i ) // print all file
names recursively, default could be both dirs and files
  cout << i->leaf();

My motivation for this is that

1. the manual implementation of the recursion can require a bit tweaking to
get right
2. other languages seem to provide such features, eg. os.walk() in python.

If people like the idea, I can provide a starting point implementation.
