====== Cloudformation for Terraform State Files and Lock Table ======

Terraform requires a state bucket and lock table before it can do any work, but you can't create these in Terraform because it needs them to do anything.... vicious circle.

I've used Cloud Formation to create these, then Terraform will work as expected.
