Moved port number to a static, and added it to the server start log message.
Updated yaml to use 1.2's authorizer.
Issue #61
Here is my best stab at an eclipse style xml.

Java Conventionts + 2 space indent + spaces only + 120 character line width
Removing eclipse file. (just saw the one added in src/main/resources)
Example shell scripts demonstrating curl commands that perform the operations.
Fixed error handling for existing keyspace.
(To reproduce, run examples/create_keyspace.sh twice)

Protecting against NPE in the request handler.
Not sure why there is no opResult, but we probably want to avoid hitting an NPE.
Merge pull request #143 from boneill42/virgil-rest-handler

Example shell scripts (curl's) and a couple other cleanups.
