cerebroui is intended to be used as a sample application for cerebro, but
should be executed while cerebro is running.

cerebro is a service, not an application and as such it requires root
privileges to execute. Chief among the reasons for elevated privileges is the
use of raw sockets and the attachment to org.laptop.cerebro dbus interface.
