We want to create a simple example of two communicating tasks.
The first task, client will have the environment create an instance of the second task, server
client will then ask server to display a message “Hello”, and wait for an acknowledgement back from server
client then has a second server started and has it display “Goodbye”
client goes to sleep 5 seconds and starts all over, 10 times.
server displays messages, acknowledges, and dies
