----------------------------------------

See https://gist.github.com/karreiro/eade2f63ce8bdbc6d76c5b59ec7ead77
{code}
// -- Data Object

class Person {
  private UUID id;
  private String name;
  private Address address;
}

// -- Dependent Data Objects

class UUID {
  private Integer value;
}

class InternalCache {
  private UUID id;
  private Map<String, String> values;
}

class Cache {
  private InternalCache internalCache;
  private UUID id;
}

class Context {
  private Cache cache;
  private UUID id;
}

class Entity {
  private UUID id;
  private Context ctx;
  private org.apache.commons.Bla bla;
}

class City {
  private Entity entity
  private String cityName;
}

class Address {
  private String street;
  private City city;
}

// -- Expected Data Type

- Person
  - id (structure)
    - value (number)
  - name (string)
  - address (structure)
    - street (string)
    - city (structure)
      - entity (structure)
        - id (structure)
          - value (number)
        - ctx (structure)
          - id (structure)
            - value (number)
          - cache (structure)
            - internalCache (Any) // <- We don't inspect after the 5th level
            - id (structure)
              - value (number)
        - bla (Any) // <- We don't inspect non-data-object types
      - cityName (string)

> Create backend service that receives a Data Object and generate a Data Type.
> Service characteristics:
> - The service supports only Data Objects from the current project (it won't support external dependencies)
> - The imported data object is analysed with 5 levels of introspection
> - Simple java types are mapped to built in DMN data types, Integer, Double -> number, String -> string, etc. But, fields that cannot be inferred are considered “Any”
