getField, setField in org.apache.gora.avro.PersistentDatumReader

[buzz heavyyear]

Hi,
I'm busy reading through your excellent code, compiling various snippets to 
understand how things work and I'm having problems in trying to compile 
PersistentDatumReader - it's unable to find getField(record, name, pos) and 
setField(record, name, pos, ....) in Object readRecord(Object old, Schema 
expected, ResolvingDecoder in);
I have a feeling that I've missed an installation step somewhere. Could anyone 
give me a pointer on what I should have done to get this to compile.
Thanks,Nick.
