Because, formerly, comment threads were instantiated by low-level diff builder instances, they needed to be parameterized with information that was only relevant to the thread groups (namely the project name and the parent index). This resulted in tight coupling between gr-diff-builder and both gr-diff-comment-thread-group and gr-rest-api-interface. To decouple the builder from these two implementations, thread creation is relocated to the gr-diff level and a create function is passed down into the builder.
