Implement take

[William Ayd]

Not sure if there is an equivalent way to sort an array by another, but numpy has take as a convenience function:

While ndarray has slice and to_slice methods, I don't think these are round-trippable the same way that take would be, since to_slice returns a primitive slice whereas slice looks for a SliceArg argument

I think what you are searching is select, no?

Ah thanks - yea I think that works. Appreciate the guidance
