/**
 * 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.
