CI Debug Notes

To validate some circleci stuff, I was able to run a “build locally” using the steps below. The local build runs in a docker container.

(Once) Install circleci client (brew install circleci)
Convert the “real” config.yml into a self contained (non-workspace) config via:
```
circleci config process .circleci/config.yml > .circleci/local-config.yml
```
Run a local build with the following command:
```
circleci local execute -c .circleci/local-config.yml --job 'build'
```
Typically, both commands are run together:
```
circleci config process .circleci/config.yml > .circleci/local-config.yml && circleci local execute -c .circleci/local-config.yml --job 'build'
```
With the above command, operations that cannot occur during a local build will show an error like this:
```
... Error: FAILED with error not supported
```
However, the build will proceed and can complete “successfully”, which allows you to verify scripts in your config, etc.

If the build does complete successfully, you should see a happy yellow Success! message.
