Interactive visualizations with JS

[breznak]

Hello,

I'm aware it's not a primary focus of your repo and that you already have a plotting mechanism in place. I'm following your work 👍 and thought https://github.com/nupic-community/nupic.visualizations might integrate with your repo and offload the visualization functionality/use alternative for interactive browsing. The app can run in the cloud, so users can just upload their CSV from Matlab.

Please let me know what do you think?
Cheers,
