This is waaay cool! I was seeing some errors when calling docker build on macos.

Found this: https://discuss.circleci.com/t/circleci-build-local-machine-fails-when-using-setup-remote-docker/15487 and: https://stackoverflow.com/questions/45796661/docker-permission-denied-while-trying-to-connect-to-docker-daemon-with-local-ci I'm working on a diff that fixes things 'nuff to allow my local CI build to succeed - basically by running 'sudo docker' when local.

For reference, here's the command I'm using to run a local CI build:

circleci config process .circleci/config.yml > .circleci/local-config.yml && circleci local execute -c .circleci/local-config.yml --job 'build'
