Thanks for splitting the files. I agree that it would make sense to move out the ContinuationEntry functions out of the ContinuationHelper files. I hope you get to that after this change.

There are number of inconsitencies in whitespace, include guards, and include orders. I've fixed those as a patch on top of your changes:

Would you mind including those in your PR?

Thanks
