Clear Out is Circulate followed by centers Couple up while the ends
"Like a Couple Up". That is, the ends U-Turn Back if needed to
face into their box of 4.
Since this starts with a Circulate, it is subject to the C2 "anything
anything" rules. A circulate modifier may be given, as in "Bias
Clear Out", or a call may be given, as in "Percolater's Clear Out".
