Machine Learning library comparisons for testing brain architectures

There are already nice ML comparisons out there:

1. https://en.wikipedia.org/wiki/Comparison_of_deep_learning_software

Here, I compare free ML libraries for suitability of use in archibrain.
Particularly, we want
0. python / julia support

1. arbitrary even spiking neurons
2. auto-differentiation of arbitrary functions
3. ease of implementing different learning algos (not just backprop) - almost Brian style.
4. can use GPUs (and CPUs) across multiple nodes (openmp/cuda/opencl?).
5. ease of implementing both RL and supervised learning tasks.
