sym assembly model lacks metal coordination pbonds

[Elaine Meng]

open 4gbc
... see two metal-coordination pbonds
sym #1 assem 1
... model #2 has no metal-coordination pbonds, not even in the full atomic part (one dimer of the hexamer)

Then if (using the Models checkboxes) I hide #2 and show #1 again, I can't see the metal-coordination pbonds in #1 any more, even though they are supposedly shown. Command "show pseudobonds" fails to show them as well.

Fixed the problem that the metal-coordination bonds of the original assembly won't redisplay.

The symmetry copies don't seem to be copying pseudobond submodels. Will look into that.

[Tom Goddard]

The symmetry model copy does not have metal coordination bonds because those are per-coordinate set pseudobonds and per-coordinate set pseudobonds are not yet copied by the Structure.copy() method (in C++ code). Also the coordinate set coordinates are not copied by the copy() method.

Reassigning to Eric to add copying coordinate sets and per-coordinate set pseudobond groups.
