This example application implements a simple PPI application: It will read UDP packets from an
input port and will forward them to another port at a fixed packet rate. If the input stream
does not provide enough packets, empty UDP packets will be sent instead.

\section run Running the example
Running the example is a little bit more complicated since we need to provide example UDP

# nc -u -l -p 44345

The next command starts the \c ratestuffer

+ First the needed modules are declared. We have
- the \a barrier to discard incoming packets sent to fast
- the \a queue to receive incoming packets and create throttling notifications
- the \a generator to create the stuffing packets
The constructor now initializes all the local objects. We pass the template \a packet to the \a
generator and set the timing \a interval of the \a rateFilter.

The \a input and \a output connector references are bound to the corresponding connectors we
want to expose: \a input to the \a barrier's \a input and \a output to the \a rateFilter's \a
output.
\until udpSink
The \ref senf::ppi::connect() calls setup the necessary connections.

The module setup is complete, \ref senf::ppi::run() is called to enter the event loop.
