Publishing NPM packages

Package publishing happens automatically through CircleCI whenever changes are checked in to master. The only setup needed is to set an NPM_TOKEN environment variable in CircleCI with a token authorized to make access to the ArgoDigital organization.

Steps to publish:

1. Determine what kind of change is being made following semantic versioning conventions
2. Update package.json with the appropriate package number
3. Deploy into or merge into master to initiate the publishing workflow
