@NimaSarajpoor I think this is ready to be reviewed (I know you are super busy so no rush). Please feel free to ask any questions as I'm sure I missed many things since I've stared at it for so long :)

[seanlaw]

@NimaSarajpoor I've made some changes based on your suggestions

[seanlaw]

Btw, I was wondering if you would like to update the README as well

No, since it is experimental, I would consider adding it in the future IF ray (and numpy, scipy, and numba too) has no issues after 2-3 version updates.

[seanlaw]

This should be my last set of comments! That was one big PR with huge amount of effort you put behind it!

@NimaSarajpoor Please feel free to squash and merge if you feel that it is ready. Everything looks good on my part. Thank you for your help!

@seanlaw Done! (Thanks for the challenge!)
