It's the Matrix-Movie green ;)

I only implement reading the file format.
And a few convenience functions for finding a table, iterating by 
rows, and extracting columns.

The cause for the different results it like the scheduling of the 
OS.
Since we do issue quite a large read before iterating.
most of our time-slice has been used.
which makes it possible for us to get swapped out during 
processing.
