This document describes extractors. Those extractors are intended to combine
*independent* sources with weak entropy.
None of our sources we have in add_*_randomness are independent.
In addition, I am not sure why this research is so hyped. I think that the 3-
source extractor described in [1] is more efficient and easier to implement
