> This currently doesn't work because Player depends on Position, but it should:

> $ cat position.avsc 
> {"type":"enum", "name": "Position", "namespace": "avro.examples.baseball",
>     "symbols": ["P", "C", "B1", "B2", "B3", "SS", "LF", "CF", "RF", "DH"]

>   "fields": [
>    {"name": "number", "type": "int"},
>    {"name": "first_name", "type": "string"},
>    {"name": "last_name", "type": "string"},
>    {"name": "position", "type": {"type": "array", "items": "avro.examples.baseball.Position"} }
