[x] Getting nested relationship queries working

Tried performing recursive Neo4j Cypher query, but the GraphQL response returned a flat array of Concepts (rather than an array of nested Concepts) - example:
```
allConcepts: [Concept] @cypher(
	statement: "MATCH (this)-[:TEACHES *1..]->(c:Concept) return c"
)
```

So now I've implemented the approach recommended by Facebook: manually query n levels deep (in this case, I've made the queries go 5 levels deep in Concepts) and then later load another n levels deeper if you need to - example:

fragment concept on Concept {
  ...conceptWithoutChildren
  concepts {
    ...conceptWithoutChildren
    concepts {
      ...conceptWithoutChildren
      concepts {
        ...conceptWithoutChildren
        concepts {
          ...conceptWithoutChildren
          concepts {
            ...conceptWithoutChildren
          }
        }
      }
    }
}

[x] Create sample queries
[x] Create sample mutations
[x] OrientDB ⇒ Neo4j migration
- Possible approaches:
  1. Migrate OrientDB ⇒ Neo4j and then refactor schema
  2. Refactor OrientDB schema and then migrate it to Neo4j
  3. Export OrientDB ⇒ JSON file, parse and convert it using a custom script, then import to Neo4j
- [x] Export OrientDB data
- [x] Import data to Neo4j
- [x] Simplify schema
[x] Neo4j ⇒ OrientDB migration (reverse) for backwards-compatibility
