/**
* Creates a function which is a composition of the passed asynchronous
* functions. Each function consumes the return value of the function that
* follows. Composing functions `f()`, `g()`, and `h()` would produce the result
* of `f(g(h()))`, only this version uses callbacks to obtain the return values.
*
* Each function is executed with the `this` binding of the composed function.
