Modification of the example code

To illustrate the fact that we can share code seemlessly with different
scheduling behavior, at ease with futurist. Moreover, the example code
shows how the concurrency/parallel execution can be observed from same
code, just by changing the executor. This demonstrates the power of
futurist interfaces.
