[Cross] Clover the Horn

This starts like Cloverleaf (or Cross Cloverleaf) and ends like Round the Horn. The leads finish the Cloverleaf and Pass Thru with each other in the center. The trailers don't do the final 1/4 turn of the Cloverleaf — when they find themselves facing each other on the outside, they Pass Thru.
