Also, could we change the name of this file from de.jl to lotka_voltera.jl?

Looks like the neural_odes.jl change is WIP? I went ahead and merged the lotka volterra changes as that's a really nice demo.

end

model = Chain(downsample,u->n_ode(u,25.)[:,:,:,:,1],classify)
model = Chain(downsample,u->n_ode(u,[25.])[:,:,:,:,end],classify) # Further ugliness getting sol[end]

on the newest versions of DiffEqFlux it should just give sol[end] in this case without the extra dimensions?

The DQN example for the CartPole environment and the environment itself has been updated to stop converting the actions (`Discrete(2)`) to `{-1, 1}`. Please refer to this [PR](FluxML/Gym.jl#29) for more details
This change fixes an error I got and which seems to be due to the multiplication with 0.1 (Float64) converting the array to Array{Float64}

I realized that I should have made this a PR in order to discuss the possibilities. NumFocus is able to accept collections through this sponsorship link on behalf of the Julia project. The intention here is to identify the donations by project and share them back to the developers.

Please let me know if this is ok. Also, I am happy to work on setting up an alternate form of sponsorship (of the many that Github notes), or simply revert this altogether.
