people are often confused about this, in particular because our use of R^2 is possibly slightly non-standard. thanks! +1 for merge. |

What does this implement/fix? Explain your changes.
Added simple examples showing a perfect score (1.0), an expected value score (0.0), and a negative score, to show what r2 does at a glance.
Any other comments?
I'm new to machine learning and was a bit confused by R^2 - in part due to reading a description that turned out to be incorrect - so thought these examples might help others also.
