OFC code

The original C-code used in the appendix of the SOC book, including all formatting, can be compiled as follows:
cc -o ofc -O3 -Wall ofc.c
on most Linux platforms. System size etc. can be adjusted using the corresponding macros.

reference.dat is the output of ./ofc > reference.dat, which serves only as a fingerprint, not as an example for meaningful data (which would need more iterations, bigger systems etc.).
