/**
 * Initializes and executes the server components. Although the other {@link SPQRWebSocketServer#run(String)}
 * could do the same work this one allows better testing as the {@link InputStream} parameter allows
 * to inject a variable which may be controlled much better. In the case it would be necessary to 
 * provide a reference to a temporary file which is controlled by the use case ... somehow too much work ;-)
 * This one is easier.  //from   ww  w .j a  v a2  s .  c o  m
