The reviewers were generally impressed by the quality of technical contributions, but had concerns about the clarity of the work. In particular, there was a shared sense that the paper was very densely written and difficult to understand. The authors promise many revisions, which reviewers are taking in good faith. Reviewer 1 has left very detailed comments about how to revise the paper to improve clarity. Please take these very seriously and undertake to make revisions with these points in mind for a final version.
