Hi Folks,
Some notes here...
The README at sdks/php/kessel/input/README.md has been deleted in this PR. If this is not desired then please amend.
The package at lib/vendor/Apigee/Usergrid has been moved to lib/vendor/Apache/Usergrid, this is reflected in the documentation. All instances of Apigee have also been amended within the code to accommodate the package renaming.
I think that's about it.
Thanks
