Updated CND Abstract to remove word "normative"

Uploaded the new CND revision with the following abstract:

This document is intended to provide a set of representative use cases that examine the requirements on identity management functions as they are applied to cloud based interactions using commonly defined cloud deployment and service models.  These use cases are intended to be used for further analysis to determine if functional gaps exist in  current identity management standards that additional open standards activities could address.

Also, I removed the Normative/non-normative reference sections and now have only the top-level section "references".  Adjusted the ToC and fixed some minor pagination issues around tables where the header was breaking across pages making the table unreadable IMO.

Let me know if we can go with this.

Thanks,
Matt
