Ray, as I wrote in my last sentence I do not feel any pressure to
replace the current functions in src.

After coding the binary splitting versions for the constants I was
curious to check out the other algorithms described in this paper.

I thought it is worth to share the implementation of these algorithms.
Perhaps someone can use them or is simply interested to study them.

The binary splitting variants are very fast and in some far future these
implementations might be worth to consider. At the moment I don't want
to risk breaking anything in src for the sake of speed advantages.
