### New Features

 - auto-calculation of a good hex-len, like what git does
   If the `core.abbrev` value isn't set or is set to `auto`.
 - `Commit::describe()`
   A way to fluidly configure a `git describe` operation and run it.
   
   Along that, a new `Tag` top-level object was added as well to provide
   convenient access to otherwise lower-level objects. It's not strictly
   required for our implementation here but it's needed for a symmetric
   API.
