I would like to merge pull request a few things I did.

Hi sir, I needed a Pivotal Wrapper and I found your fork from another fork, I liked your fork because you upgraded to Pivotal V5. I Upgraded Newtonsoft.Json to 6.0.5 because was missing this reference and I also added new methods to get all project Epics and get all stories matching filter with pagination which I needed to use in my integration.

I would like to know if I could help with this piece of code =D?
