DocumentComposer should not handle resolution object properties such as metadata, we should refactor them out.

I think we can build the element-api and element-app as docker images, and add instructions for Azure Deployment.

Maybe we want to have a single docker image for exposing the web app and api together.

Once they are docker images, it should be easier to deploy them on other providers.

Want to add storybook, to encourage reusable components.

Observer should note "who wrote the transaction to the ledger"...
