experimental:
test_recompress.c        a tentative to recompress sensor data with better DHT tables. But I did not manage to encode DHT data in jpeg header


in src/
bits.c        bits manipulation functions. Used by lljpeg functions
bits.h        bits manipulation functions

PyCraw2.c     Python extension
setup.py                 to compile the craw2 extension under Linux and Windows SDK 7.0

dataflow is
1. opening a Canon Raw image, parse TIFF tags and image data: craw2.c and tiff.c
2. decoding lossless jpeg into RGGB or YUV data: lljpeg.c and bits.c 
3. creating an image (determining RGGB borders): rgb.c
4. interpolate / demosaicing: rgb.c or yuv.c
5. export to TIFF: tiff.c
