model training code

[sammosummo]

It would be very helpful for other researchers to share the code that was used to generate the trained models. Presumably this was primarily sklearn based. This would allow us to train models on other data sets with different demographics and include additional imaging modalities.

The training code is available as part of this repo. I have just added a note in the Readme.

The code is quite convoluted, and I am not sure how helpful this will be. It is pretty vanilla sklearn, though.

Maybe @dengemann's recent work with code will be more helpful.
