roundRobin(r1, r2, r3) yields r1.front, then r2.front, then 
r3.front, after which it pops off one element from each and 
continues again from r1. For example, if two ranges are involved, 
it alternately yields elements off the two ranges. roundRobin 
stops after it has consumed all ranges (skipping over the ones 
that finish early).

roundRobin can be used to create "interleave" functionality which 
inserts an element between each element in a range.
