Come to think of it, gromacs doesn't use "atomic radii" anywhere except
genion, and if you're planning some Poisson-Boltzmann calculations you
need to be very careful to choose radii that give sensible results with
the type of PB solver you're using. Hacking something up from VDW radii is
a great way to burn CPU cycles for no value.
