void special::addSpecialCommands(commands::CommandTree* tree)

/*
  This function should be edited if you want to add new commands to the
  system, instead of just editing the "special" command. Adding a command
  is easy : you should choose a name for it (an arbitrary string; if it
  already exists it will replace the existing command), a "tag" (used
  for help purposes; special_tag will do), a function which should take
  no arguments and return void, which will be executed by the command,
  and a help function (the empty function will do; this is already
  provided as relax_f, provided by commands.h).

  The commands are added to the main command tree of the program (the
  tree argument is used for convienience, since this function is called
  when mainCommandTree() is not yet functional); it would also be possible 
  to add special command trees, but we have decided to leave this to users 
  willing to delve into commands.c.
