Doc note:  Eventually the documentation should be updated.

Now it just says:  "If the ORC file writer selects a generic compression codec 
(zlib or snappy), every part of the ORC file except for the Postscript is 
compressed with that codec."  And the Hive ORC documentation says:  "The codec 
can be Snappy, Zlib, or none."

LZO should also be added.

This seems reasonable. Are you working on implementing the compression? I'd 
love to get the integration in so that others could experiment with them.
