Start/Stop Accelerator

The commands involved in this tutorial are ncmgr info, ncmgr start and ncmgr stop.

You should use ncmgr, especially when starting Accelerator, because it checks for and applies any daemon and DB schema changes when moving to a new version.
Note: Please remember to uses the shell where you set the NC_QUEUE environment variable to the name of your training tutorial queue.
