Now works up through 100% more iterations!

Now works up through 1 iteration. Fixed bug that was causing
correlations to be calculated incorrectly (correlation was
= instead of +=).

Need to fix issues with strange values being fed to chi2
Compiles and writes output. Unknow if correct

The program now compiles and write to the file specified. I don't
know if that output is correct.

In other news, I've moved the projection (GeoTransform) class and the
new ImageInfo class to their own file with their own namespace
(geo_utils). Fixed several minor bugs along the way, though I'd need
the git diff to tell you exactly what I did.
