/**
|
|
* 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.
|
|
*
|
|
* If the last argument to the composed function is not a function, a promise
|
|
* is returned when you call it.
|
|
*
|
|
* Each function is executed with the `this` binding of the composed function.
