Enhanced AVRO support : nested records and self describing schema

[chipmaurer]

For self describing schemas support : use the schema definition supplied for the avro formatted objects. I think you are able to determine an object schema by reading a header from the object.

For nested records, each record may include a sub-record, like a person may include name, age, etc fields, but the address may be a top level object, and the street, town, zip, etc may be the 'address' sub-record in the person object.
