Comment(by vbraun):
* `cddlib` is slow, thats a generally known fact. It basically comes out
last in every benchmark I have seen. It was the first implementation, and
nobody would have published a competing implementation if it wouldn't have
been faster...
* `random.h` has the GNU C library copyright notice. I've modified the
source to cut it down to the essentials, remove other rngs and other libc
calls.
I don't mind making `cddlib` depend on `gsl`, but the obvious arguments
against would be:
1. `cddlib` doesn't need a high-quality rng.
2. Many projects use `cddlib`, should we really try to push a new
dependency upstream?
