/** Since such classes are typically quite small and simple, all
    the implementation is inline. The macro declares
    - default constructor
    - RAII::set()
    - RAII::reset()
    - destructor
    The Set and Reset arguments are the code to run in the respective
    functions. "args" are the argument string (in parens) for the
    constructor and set.
