* Added support for provided layers

* Updated documentation.

* Oops, I don't use vcr or webmockr yet.

* Added aws_lambda_function back.

* Added class to account info.

* Oops. Put query back into the http call.

* Set up http test
But it only works when I run it locally, so then I disabled it.

* Declaring vcr and here.
I had this before but then I skip those test so I removed it, but R CMD CHECK complained.

* Switched to httptest
