          Params:
          * repo_name: If only `repo_name` is given, all commits in the repo are
          returned.
          * to_commit: Optional. Only the ancestors of `to`, including `to`
          itself, are considered.
          * from_commit: Optional. Only the descendants of `from`, including
          `from` itself, are considered.
          * number: Optional. Determines how many commits are returned.  If
          `number` is 0, all commits that match the aforementioned criteria are
          returned.
