A very basic back-end function to get Users who have posted comments on some files contained in the diffset of a review request. This is very much a work in progress. Will keep updating as I learn more about how to do things efficiently using Django db queries.

Ran the function to ensure it returned data that looked reasonable. Ran unit tests (Though I didn't add any and didn't really do anything that could break them..) But they pass regardless.
