44
   Set up the standalone simulation. Initialize the default configuration and
45
   register all the sections that may appear in a user configuration.
46
 
47
   Then attempt to parse the args, configure the system from any configuration
48
   file specified and print out the configuration used.
49
 
50
   Add a signal hander, so ctrl-C will drop the user into the CLI.
51
 
52
   The initialize the simulator, call the appropriate main simulator function
53
   and when it returns tidy up.
54
 
55
   @param[in] argc  The number of arguments to the command
56
   @param[in] argv  The vector of argument strings
57
 
58
   @return  The return code required from the simulator. This is actually
59
            achieved by calling exit() with the return code, rather than
60
            returning an explict value.                                      */
