Summary: Connect atoms according to sum of radii

Initial Comment:
Jmol has internal criteria based on atomic radii for auto-connecting atoms 
(bonds). 
bondTolerance and minBondDistance allow some modification, and specific 
distance 
ranges can also be specified. But it would be good to be able to specify a 
fractional 
range eg 0.8 to 1.2 of the sum of the pairs of atomic or ionic radii, perhaps
connect 0.8 1.2 ionic (~cations) (~anions);
connect 0.8 1.2 atomic (~cations) (~anions);
where "ionic" means use ionic radii, and "atomic" use atomic radii.
The use of ionic radii is essential for most inorganic structures.

"%" sign, not "5" sign, of course!

Message:
done. Jmol 11.9.32

connect 80% 120% {~cations} {~anions}

The "5" sign indicates we are talking about combined atomic radii. No need
for the ionic/atomic distinction -- that is taken care of by Jmol based on
formalCharge.
