/**
* Reads in Avro records of type T and adds them as the first field in a tuple.
*
* @param flowProcess The cascading FlowProcess object. Should be passed in by cascading automatically.
* @param sourceCall The cascading SourceCall object. Should be passed in by cascading automatically.
* @return boolean true on successful parsing and collection, false on failure.
* @throws java.io.IOException
