Markdown formatted summary output tasks

[sciwhiz12]

For reviewing convenience, it would be good to add two tasks to output a summary of changes/data in a readable and convenient format, such as Markdown.

The first task would take a data source (production or staging) and output a summary of the data, in an understandable format. The second task would take both production and staging data, and create a summary of changes/differences between the two, with production being the 'base' data and staging being the 'modified' data.

One use case would be some form of automation which would post (and thereafter edit) a comment with a Markdown-formatted summary of changes in Pull Requests.
