I was just looking at consistent usage. The code (or at least the tests you have) indicates that `n_divergence__` is printed in the header files of output and in the output of `bin/print`, not `n_divergent__`.

Feel free to go with one or the other. It's ok to use "divergent" as an adjective too, but if the code is generating `n_divergence__`, I'd prefer that the doc is consistent.
