minor log file string concat cleanup
added additional README on impatient getting started
added REST and HTTP versions of list column family handler
IntravertCassandraServer now deals specifically with the typed classes of keyspace and column family meta data
Move to granular handlers: Made core rest handler abstract so handleRequestAsync gets implemented by action-specfic handlers
added error message construciton handler. Might be issue with the way OperationsReq.Handler deals with JSON integers in general.
Moved statics for common request params into IntravertRestUtils
MOAR refectoring, cleanup for better control between REST dispatch and eventbus handlers
removed unused registerHandlers method as it is redundant with firing to existing handlers on event bus
