Right, I think no one is using the pure r interpreter. I think we can use
it 2 ways.
1. Create a pure r interpreter without spark support.
2. Use it another r implementing of spark and make option to allow user to
choose whatever r implementation they want to use. (Because I don't know which
r implementation is better, so I don't want to remove anyone of them)---
