sgr log [OPTIONS] IMAGE_SPEC
Show the history of a Splitgraph repository/image.
By default, this shows the history of the current branch, starting from the HEAD pointer and following its parent chain.
Alternatively, it can follow the parent chain of any other image.
--tree is passed, this instead renders the full image tree. The repository doesn't need to have
been checked out in this case.
-r, --remote : Perform operation on a different remote engine
