anchor.diff:  You can notice that we have nested documents. We can specify only the root level fields that will be imported. For example:
   
   ```
  -mongo-connector -v -m localhost:27017 -t http://localhost:7474/db/data -d neo4j_doc_manager -n test.talks -i room,session
  +mongo-connector -m localhost:27017 -t http://localhost:7474/db/data -d neo4j_doc_manager -n test.talks -i room,session
   ```
   
   In Neo4j, we will have:
  
positive.code: 
  Just a remainder, you can only specify the fields of the root document and the direct nested documents that will be imported. 
  
  
negative.code: It is also possible to combine __-i__ and __-n__ options, such as:
  
  ```
  mongo-connector -m localhost:27017 -t http://localhost:7474/db/data -d neo4j_doc_manager -n test.talks -i room
  ```
  
  Important: All nodes will always have the **_id** property.
