I can no longer maintain containers

Advantages of splitting the package:

1. There can be multiple maintainers with independent release
schedules, independent testing and benchmarking code, etc., without
stepping on each other's toes or relying on the CLC to make decisions.

2. The containers package does not currently have a unified theme.
Instead, it has a somewhat haphazard collection of container types.
Four of them (IntSet, IntMap, Set, and Map) really do feel like a
package together, and Data.Graph is essentially an extension
of/application of Data.Tree. The rest feel quite thoroughly different
from each other. Splitting the package would yield three packages that
each "make sense" independently.

3. containers is fairly large, and takes a while to build. There might
be a way to work around that to make it more convenient to work with
individual components, but in light of points 1 and 2, I just don't
think it's worth the trouble.

I think if David only wants to take responsibility for Sequence and Tree, and then that should be workable regardless, with perhaps the overall package just staying under CLC ownership for now,  or perhaps a comaintainer stepping in on the other things. More maintainers for a package tends to be better, to a point, imho.
