-With `std::future`, rust has a mechanism for requesting a computation and getting the result
-later.

-The call to `future::spawn` returns immediately a `future` object regardless of how long it
-takes to run `fib(50)`. You can then make yourself a sandwich while the computation of `fib` is
-running. The result of the execution of the method is obtained by calling `get` on the future.
-This call will block until the value is available (*i.e.* the computation is complete). Note that
-the future needs to be mutable so that it can save the result for next time `get` is called.
-
-Here is another example showing how futures allow you to background computations. The workload will
-be distributed on the available cores.
