Add usage examples

Trying to figure out how to use some of these tools, like indxparse:

python indxparse.py "\\.\C:" 0 "C:":

  File "C:\Python27\lib\site-packages\python_ntfs-0.1-py2.7.egg\ntfs\BinaryParser.py", line 79, in _
_enter__
    self._mmap = mmap.mmap(self._f.fileno(), 0, access=mmap.ACCESS_READ)
WindowsError: [Error 87] The parameter is incorrect

Is it possible to access this directly from the volume (\\.\C:)? Should the offset be 0? What is the path?

BTW, I'm trying to get a list of directory and file info from an NTFS volume running on the machine. I thought this file would be a good starting point. :)
