New cyli, cylo and ring primitives.

[Magnus Forsberg]

I created these primitives with the purpose to avoid the rotation of the corresponding ones. I hope they can be approved. If not, I send an email to the PT Admin for deletions.

I think the conclusion already is that this type of rotation inside a primitive is a no go.

Use mirrored and divided primitives instead. Your suggested a3-8cyli should be created like this instead:
1 12 0 0 0 0 0 -1 0 1 0 1 0 0 3-16cyli.dat
1 12 0 0 0 0 0 1 0 1 0 1 0 0 3-16cyli.dat
