/** @defgroup bind
 *
 * SigC::bind() alters a SigC::Slot by fixing arguments to certain values.
 *
 * Argument fixing starts from the last argument.
 * Up to two arguments can be bound at a time.
 *
 * Simple sample usage:
 * @code
 * void f(int, int);
 * SigC:Slot2<void, int, int> s1 = SigC::slot(f);
  *
 * SigC::Slot1<void, int>  s2 = SigC::bind(s1,1);
 * s2(2);  // call f with arguments 2,1
 * @endcode
 *
 *  Multibinding usage:
 *
 * @code
 *  void f(int,int);
 *  SigC::Slot2<void, int, int> s1 = SigC::slot(f);
  *
 *  SigC::Slot0<void>  s2 = SigC::bind(s1, 1, 2);
 *  s2();  // call f with arguments 1, 2
 * @endcode
 *
 *  Type specified usage:
 *
 *  @code
 *  class A {};
 *  class B : public A {};
 *  B* b;
 *  SigC::Slot0<void, A*> s1;
 *
 *  SigC::Slot0<void> s2 = SIgC::bind(s1, b);  // B* converted to A*
 * @endcode
 *
 *
 * SigC::bind_return() alters a Slot by fixing the return value to certain values
 *
 * Return value fixing ignores any slot return value.  The slot is
 * destroyed in the process and a new one is created, so references
 * to the slot will no longer be valid.
 *
 * Typecasting may be necessary to match arguments between the
 * slot and the bound return value.  Types must be an exact match.
 * To ensure the proper type, the type can be explicitly specified
 * on template instantation.
 *
 * Simple sample usage:
 * @code
 * void f(int, int);
 * SigC::Slot1<int, int, int>  s1 = SigC::bind_return(slot(&f), 1);
 * std::cout << "s2: " << s1(2, 1) << std::endl;
 * @endcode
 *
 * Type specified usage:
 * @code
 * class A {};
 * class B : public A {};
 * B* b;
 * SigC::Slot1<void> s1;
 *
 * SigC::Slot0<A*> s2 = SigC::bind_return<A*>(s1, b);  // B* must be told to match A*
 * @endcode
 *
