This group of Slide Right Contras are all based on a single type of progression.

Slide Right:  For the Slide Right each couple moves to their right along the 
line or around the end into the spot of the next couple.  Middle Couples will 
completely pass a couple in the opposite line during the Slide Right.

Odd Couples:  If there is an odd number of couples, place the spare couple 
facing up the center at the far end.  When the Slide Right occurs they are part of 
the action moving one couple in and one couple out.
