/* 
  This class is the entry point of the rasdaman server. It's the interface of the server to the outside world
  It's functions are called by the communication level.
  
  For now the class inherites HttpServer which inherites ServerComm, but only to have nice acces to the stuff
  found there. Later we will drop both of them and make the life easier.
