/** @defgroup compose compose()
* sigc::compose() combines two or three arbitrary functors.
* On invokation parameters are passed on to one or two getter functor(s).
* The return value(s) are then passed on to the setter function.
*
* @par Examples:
* @code
* float square_root(float a) { return sqrtf(a); }
* float sum(float a, float b) { return a+b; }
* std::cout << sigc::compose(&square_root, &sum)(9, 16); // calls square_root(sum(3,6))
* std::cout << sigc::compose(&sum, &square_root, &square_root)(9); // calls sum(square_root(9), square_root(9))
* @endcode
*
* The functor sigc::compose() returns can be passed into
* sigc::signal::connect() directly.
*
* @par Example:
* @code
* sigc::signal<float,float,float> some_signal;
* some_signal.connect(sigc::compose(&square_root, &sum));
* @endcode
*
* For a more powerful version of this functionality see the lambda
* library adaptor sigc::group() which can bind, hide and reorder
* arguments arbitrarily. Although sigc::group() is more flexible,
* sigc::bind() provides a means of binding parameters when then total
* number of parameters called is variable.
