We do insist that drivers are stable (not sorted, just stable) and that
refine is also stable, which allows us to promise a stable output.
I also changed refine so it returns the root set in the same order that
the original root id list was supplied, as this seems to be a strictly
better experience.

Errors relating to a particular package (as opposed to the Load
operation as a whole) are now only recorded in the Errors
field of the corresponding Package.
Clients are responsible for printing or otherwise handling errors.
This is a breaking API change.
The PrintErrors function prints all accumulated errors,
dependencies first, and is provided for convenience.
PrintErrors is based on Visit, another helper function, which
visits each Package in an import graph.
Also:
- add an Example documenting typical use.
- update clients to handle errors explicitly.
