Changes for release 2013_06_a
Enrollment Example did not work due to Mandatory Smart Product inclusion in the Package. I am not sure the root cause of the defect. (Lost Optional flag, change in default behavior, or missing smart product in enrollment creation)
SUBMODULE UPDATED: SoftwareDevelopmentKit
US2784: The SSO example project has been added to the Metanga-RESTful-SDK repository.
Merge upstream into the fork.
1) Projects have been updated up to .Net Framework 4.5;
