Log-polar transformation first attempts.
He..
X!
stage stuff
verified that phase correlation works.

Tested with images of head from:
http://nashruddin.com/phase-correlation-function-in-opencv.html/

BUT: only works if head2.bmp is the pattern and head1.bmp is the image.
Also cropped them down to 128x128 first.

Tested matlab code from:
http://thilinasameera.wordpress.com/2012/03/24/translation-invariant-image-registration-using-phase-correlation-panorama-imaging-on-matlab/
=> gives same result.
will try to use fftw3 now..
Fix the freakin' log polar coordinates!!!!
finally... some sensible results...
add complex_num.h
WORKS! NEED TO RECOVER SCALE/ROTATION NOW.
add log_polar.h
foo
new headers
f
match.c
add test images..
Leftover changes
