> We currently have a rudimentary way to print HLog data, but it is limited and currently prints key-only information. We need extend this functionality, similar to how we developed HFile's pretty printer. Ideas for functionality:
> - filter by sequence_id
> - filter by row / region
> - option to print values in addition to key info
> - option to print output in JSON format (so scripts can easily parse for analysis)
