How do you change the radius?
I had a long chat to Bernhard about this. My feeling is that in order to avoid
"user consternation" ((c) George Sheldrick), RS refinement in Coot should
_never_ move something into space already occupied by another part of the same
molecule (zero occupancy excepted). I realise there are implementation
difficulties, but I do think this is a major problem.
