Add a custom CloudFormation stack output with CDK

Once we deploy static assets to an S3 bucket it's good to know, well, where are they exactly - saying that "they're in the cloud" is not a good answer.

In this quick lesson we're going to learn how to create a custom CloudFormation stack output in order to output the path to an egghead logo in order to add it to our app.
