/**
 * Compiles all user-defined custom fragments into "node fragments".
 *
 * "Node fragment" is a fragment that:
 * 1. Is defined on gatsby node type
 * 2. Is "shallow", meaning that all deep selections of other nodes
 *    are replaced with references
 *
 * For example:
 *
 * fragment Post on Post {
 *   title
 *   author {
 *     firstName
 *     email
 *   }
 * }
 * fragment User on User {
 *   lastName
 *   recentPosts {
 *     updatedAt
 *   }
 * }
 *
 * Is compiled into a map:
 * "Post": `
 * fragment Post on Post {
 *   title
 *   author {
 *     __typename
 *     id
 *   }
 * }
 * fragment User__recentPosts on Post {
 *   updatedAt
 * }
 * `,
 * "User": `
 * fragment User on User {
 *   lastName
 *   recentPosts {
 *     __typename
 *     id
 *   }
 * }
 * fragment Post__author on User {
 *   firstName
 *   email
 * }
 * `
