Can you think of anything else we might move into this directory? Having a base
subdirectory with one file in it seems not that great. If there isn't much more
we can move there, maybe just put it in containers?

One thing to consider might be to move the code in //base/containers/adapters.h
to //base/algorithm/reverse_adapter.h

After your previous suggestion, I removed this directory.
