[r-t] All the 4-runs

[Simon Gay]

It looks like an interesting proof of concept, but would be difficult to 
ring.

I wonder whether there is any useful structure within it - it's not 
obvious from the way it is set out in CompLib, but maybe there is 
something there.

It would be good to see a more structured composition, perhaps organised 
into blocks along the lines of the maximus particles compositions.

For example, a cyclic 8-part built out of blocks with dodging on four 
bells and hunting on the other four, that kind of thing.
