 scandir, a better directory iterator and faster os.walk()
 
-scandir() is a directory iteration function like os.listdir(), except
-that instead of returning a list of bare filenames, it yields DirEntry
-objects that include file type and stat information along with the name.
-Using scandir() increases the speed of os.walk() by 2-20 times
-(depending on the platform and file system) by avoiding unnecessary
-calls to os.stat() in most cases.
