@SleepyThread - great feature!
Building on @felixcheung's comment, it would be good if Snapshot feature
would use org.apache.zeppelin.notebook.repo.GitNotebookRepo to store a
snapshot/revision, so then you could compare revisions etc.
ps. Looks like commits should be slashed? It shows unrelated commits in
this PR.---
