Tutorial updates pass 2.

- The previous move of the examples meant the Jar file no longer
included them, update the main POM to make sure the classes and
resoruces are in the correct place. 
- Clean up the example classes to make the hibernate annotations cleaner
and more correct. 
- Add more data (saved and printed) to the Tutorial.
This is moving files around to match the requested update to put the
tutorial in a separate directory.
Fix the artifact ids to be consistent with the larger artifact naming
standards.
