Nevermind, I didn't realize that the first argument to the reader could be null.  Oops.

 I keep getting a ClassCastException that a Builder cannot be cast to a Message whenever I
try to deserialize an object with the ProtobufDatumReader after it was serialized with the
ProtobufDatumWriter.  I've looked through the code a bit in ProtobufData and GenericDatumReader
but I'm not sure how it's supposed to work because it appears to just be creating a new builder
and then passing it to a method that attempts to cast it to a message.  I've got a small example
project here (https://bitbucket.org/willgorman/avro-proto-test) with a test that recreates
the error.  I've been able to do the same thing successfully using avro-thrift.  Is there
anything that I'm doing incorrectly here?
