LFSR: roundup

After a couple of days of tinkering in the Scheme lab, thinking about
algorithm complexity and being distracted by HOP for prototyping
(which works nice btw..) it's time to get something done. Tasks:

  (A) lens distortion estimation from running example.

  (B) grid parameter estimation

Approach: do both based on Hough transform. First one: local tx,
second one: global tx with transformed coordinates. I do need move
from Scheme to C code because I'm running into trouble with execution
time. HOFs are nice, but parametricity is slow..
