This adds Root Mean Square Deviation method (https://en.wikipedia.org/wiki/Root-mean-square_deviation).

Any other comments?

Added Root mean square deviation (https://en.wikipedia.org/wiki/Root-mean-square_deviation) using numpy.sqrt() and previously defined mean_squared_error.

Needs pep8 and tests. I'm not sure it's worth adding a variant that's just different by the sqrt. Can you just do this post-processing?

Let's make this a parameter to MSE, perhaps... is it worth adding a neg_rmse scorer? It seems a bit strange since sqrt is monotonic
