Done. Rachel has been correctly identified as author in the relevant parts
up to commit 98fe74218d. After that, she had offered review comments and I
have taken the liberty to add her as a reviewer through out.

Also I think that Shi Yu should be credited as a reviewer of 0003.

Please find in the attached v30 an updated message, as well as an amended
reviewer list. Also v30 addresses the final comments raised by Justin.

Cheers,
