This component is based on discovery of DDS signals through DDS built-in topics. It outputs a list of running nodes, where a node
is a spliced
instance. In shared memory mode, this will be a splice daemon process managing the domain. In single process mode each application will be a node
.
The executable takes one arguments which evaluates to a boolean true/false. It sets the automatic
variable, defining if the process should wait for nodes to connect or exit immediately.
