[Chimera-users] Just want atom distances

Good idea. I've implemented a version of this by adding an entry to
the popup menu you get when you control-double-click an atom. The
menu will have a "Show distances to nearby atoms" entry that shows all
distances to non-bonded atoms within 4 angstroms (and hides distances
you showed previously). If you bring up the menu a second time on the
same atom the entry will be "Hide...(etc)". The feature will be in
tonight's daily build. The actual menu text isn't set in stone so it
might change slightly in the next few days but it'll still be obvious
which entry it is.
