    This is designed to be easy to add another type to the arguments... 
    All you have to do to do so, is add an enum to the Type enum, add a 
    newType getNewType(void), add a void setNewType(newType nt), and add
    a case statement for the newType to ArArg::print.  You should probably also
    add an @see newType to the documentation for ArArg::getType.
