I made changes to deal with async code, get test cases to work and other items. I tried to update all PR comments so they are in sync with these changes and resolved as appropriate. Some comments are marked outdated due to shifting line so @kramosss let me know if it is unclear what they apply to.

I updated the code and it should have all the changes, feel free to let me know if I missed something or if there are any other changes to be made.
