Boost Filesystem Version 3

I've been looking at the boost filesystem as a possible replacement for file manipulation and directory parsing.

In doing so I discovered that the comparison operator for boost::filesystem3::path is horribly slow. I'm not entirely sure why, it may be the iterator.

In doing this I implemented a simplistic wrapper to avoid the massive include load. The filesystem 3 path.hpp include looks like it includes well over 100,000 lines of headers. My wrapper runs only about 30,000 lines almost all of which is because I'm including <string>

In my operator< comparison function I replaced the compare with a .native() string comparison and found what appears to be about a 10X improvement in performance on the Mac.

The more I dig into boost the more I'm convinced that it must be used with extreme caution.
