[RE-wrenches] SunEye 210

[Dan Fink]

Here are two examples of my test SolarShades app results, taken from the
same spot on a roof, one on my first try and one after some practice. You
will see the obvious difference in the results. Some sort of tripod mount
would be the key to making this app useful on a professional level, though
I still find it useful for quick assessments.
