//
//  composite class
//
//      A composite is an actor base class composed of zero or more
//      actors (see actor.hpp) and an operation. A composite is itself
//      an actor superclass and conforms to its conceptual interface.
//      Its eval member function un-funnels the tupled actual arguments
//      from the tuple by invoking each of the actors' eval member
//      function. The results of each are then passed on as arguments to
//      the operation. Specializations are provided to handle different
//      numbers of actors.
//
//      Schematically:
//
//          actor0.eval(tupled_args) --> arg0 --> |
//          actor1.eval(tupled_args) --> arg1 --> |
//          actor2.eval(tupled_args) --> arg3 --> | --> operation(arg0...argN)
//            ...                                 |
//          actorN.eval(tupled_args) --> argN --> |
//
//      The operation can be any suitable functor that can accept the
//      arguments passed in by the composite. The operation is expected
//      to have a member operator() that carries out the actual
//      operation. There should be a one to one correspondence between
//      actors of the composite and the arguments of the operation's
//      member operator().
//
//      The operation is also expected to have a nested template class
//      result<T0...TN>. The nested template class result should have a
//      typedef 'type' that reflects the return type of its member
//      operator(). This is essentially a type computer that answers the
//      metaprogramming question "Given arguments of type T0...TN, what
//      will be its operator()'s return type?".
//
//      There is a special case for operations that accept no arguments.
//      Such nullary operations are only required to define a typedef
//      result_type that reflects the return type of its operator().
//
//      Here's an example of a simple operation that squares a number:
//
//          struct square {
//
//              template <typename ArgT>
//              struct result { typedef ArgT type; };
//
//              template <typename ArgT>
//              ArgT operator()(ArgT n) const { return n * n; }
//          };
//
//      As can be seen, operations can be polymorphic. Its arguments and
//      return type are not fixed to a particular type. The example
//      above for example, can handle any ArgT type as long as it has a
//      multiplication operator.
//
//      Composites are not created directly. Instead, there are meta-
//      programs provided that indirectly create composites. See
//      operators.hpp, binders.hpp and functions.hpp for examples.
