Girls Face Right
(VDC: Put on Same Line & Create Snapshot record?)

at the (*) I would expect a Z-formation 
a) can you change CSDS to get the expected resulting Setup
b) Could you implement a Command "Check a Z" that will force 
the dancer in the named Formation (Others would be "check Lines" 
or "Check a Galaxy" or "Check Diamonds" or "Check Facing Diamonds" 
...) and if the dancers are in the named formation , CSDS will say 
okay , nothing to do but it is a legal call and can be entered 
without () and will not be treated as a comment
