unmarked as a Work In Progress

changed the description

The new CASCache and ArtifactCache APIs added in !922 (merged) make this work better, but in the absence of an API to only checkout a subtree or for the CASCache to own extraction caching wholly rather than for it to be determined by parts of the ArtifactCache, there's some ugly code to attempt to extract artifacts to the same place they would be extracted to if extracted by either ref or artifact.

Aside from the tiny nitpick on the comment, this looks good. I'm happy with the changes to _casbaseddirectory and they make the import test cleaner too - many thanks!
