Bina Research Trees Are Not a Good Fit for the Disk

B bindr research trees are not a good fit for the disc because they have very low fan out and potentially bad locality.

In bina research tree, we have a single key per note. But unlike biner research trees, bee trees have not just two children, but have many.
