Validate the example

Save the example as node.json in the repository root, then run:

node -e "const { SHACLValidator } = require('./packages/robos-graph/lib/shacl-validator'); console.log(new SHACLValidator().validate([require('./node.json')]).conforms)"

The command prints true when the node meets every rule for its types.
