Convenience wrapper for the numbered sigc::signal# templates.
Like sigc::signal but the additional template parameter T_accumulator defines the accumulator type that should be used.
An accumulator is a functor that uses a pair of special iterators to step through a list of slots and calculate a return value from the results of the slot invokations. The iterators' operator*() executes the slot. The return value is buffered, so that in an expression like
the slot is executed only once. The accumulator must define its return value as result_type
.
