> This is a barebones patch for AvroStorage which enables support of multiple
> input schemas. The assumption is that the input consists of avro files
> having different schemas that can be unioned, e.g., flat records.
> A simple illustrative example is attached
> (avro_storage_union_schema_test.tar.gz): run create_avro1.pig, followed by
> create_avro2.pig, followed by read_avro.pig.
