<dd><p>This class is used to initialise access to Reticulum within a
program. You must create exactly one instance of this class before
carrying out any other RNS operations, such as creating destinations
or sending traffic. Every independently executed program must create
their own instance of the Reticulum class, but Reticulum will
automatically handle inter-program communication on the same system,
and expose all connected programs to external interfaces as well.</p>
<p>As soon as an instance of this class is created, Reticulum will start
opening and configuring any hardware devices specified in the supplied
configuration.</p>
<p>Currently the first running instance must be kept running while other
local instances are connected, as the first created instance will
act as a master instance that directly communicates with external
hardware such as modems, TNCs and radios. If a master instance is
asked to exit, it will not exit until all client processes have
terminated (unless killed forcibly).</p>
<p>If you are running Reticulum on a system with several different
programs that use RNS starting and terminating at different times,
it will be advantageous to run a master RNS instance as a daemon for
