--------------------------------------------------------

Hi Lewis,

This is not such a large patch mate ;) 
Well, what this does is that it allows us to support data types like {"name": 
"content", "type": ["null","bytes"]} So what it is doing right now is that I am 
letting the CassandraStore class to store the position of the non-null type, 
and use it to figure out the correct serializer. 
This probably seems like a big patch because it contains the final version of 
GORA-174 which I think we should commit. In this manner, we can proceed in 
creating a single smaller patch that addresses this Gora-Cassandra issue.
I will open different JIRA issues for the other data stores (Accumulo, MySQL, 
DynamoDB, etc, etc) IMHO we should address the most popular ones (HBase, 
Cassandra, and MySQL) so we can let Nutch continue functioning. What do you 
think? What do others think? (:
