/** Top level teletext application
 *  @brief Load the configuration, initialise the service and run it.
 * @detail This can be run without parameters in which case it will use the defaults in configure.
 * If a parameter is given then it replaces the defaults.
 * @todo Define options for overriding the config file settings, and the config file itself,
 * This will include path to pages, header packet, priority etc.
 * Example: vbit2 --config teletext/vbit.conf
 * Compiler: c++11
