Explanation for Training and Classes about cranium

My mistake, I forgot to write a unit test for that function.

It should be assert(classes->cols == network->layers[network->numLayers - 1]->size);.

Feel free to send a PR or I can fix it later on my own.

I made quite a few other changes including support for doubles or floats, CUDA BLAS, and renamed a lot of stuff. A PR would be a huge change for you.

Thanks for fix!
