    * @ingroup functors
    *
    *  Binders turn functions/functors with two arguments into functors
    *  with a single argument, storing an argument to be applied later.
    *  For example, a variable @c B of type @c binder1st is constructed
    *  from a functor @c f and an argument @c x. Later, B's @c
    *  operator() is called with a single argument @c y. The return
    *  value is the value of @c f(x,y). @c B can be @a called with
    *  various arguments (y1, y2, ...) and will in turn call @c
    *  f(x,y1), @c f(x,y2), ...
    *
    *  The function @c bind1st is provided to save some typing. It takes the
    *  function and an argument as parameters, and returns an instance of
    *  @c binder1st.
    *
    *  The type @c binder2nd and its creator function @c bind2nd do the same
    *  thing, but the stored argument is passed as the second parameter instead
    *  of the first, e.g., @c bind2nd(std::minus<float>(),1.3) will create a
    *  functor whose @c operator() accepts a floating-point number, subtracts
    *  1.3 from it, and returns the result. (If @c bind1st had been used,
    *  the functor would perform <em>1.3 - x</em> instead.
    *
    *  Creator-wrapper functions like @c bind1st are intended to be used in
    *  calling algorithms. Their return values will be temporary objects.
    *  (The goal is to not require you to type names like
    *  @c std::binder1st<std::plus<int>> for declaring a variable to hold the
    *  return value from @c bind1st(std::plus<int>(),5).
    *
    *  These become more useful when combined with the composition functions.
    *
    *  These functions are deprecated in C++11 and can be replaced by
    *  @c std::bind (or @c std::tr1::bind) which is more powerful and flexible,
    *  supporting functions with any number of arguments.  Uses of @c bind1st
    *  can be replaced by @c std::bind(f, x, std::placeholders::_1) and
    *  @c bind2nd by @c std::bind(f, std::placeholders::_1, x).
