constructor(rootNodeModel, context) {
    this.nodeModel = rootNodeModel
    this.context = context
  }
Utility to get a field value from a node, even when that value needs to be materialized first (e.g. nested field that was connected via @link directive)
@param {Node} node
@param {string} fieldPath
@returns {any}
@example
// Example: Via schema customization the author ID is linked to the Author type
const blogPostNode = {
  author: 'author-id-1',
  // Rest of node fields...
}

getFieldValue(blogPostNode, 'author.name')
