Exercise

For this week's exercise, we're going to build a small <q>microservice</q> that can be sent strings and will reply with those strings, upcased.

• Create a new process in the same way that we did in the PingPong episode.
• Send the process messages like {"some string", self}
• The process should pattern match out the string and the process id from the 2-tuple in the message.
• It should then call String.upcase on the provided string, responding with {:ok, "SOME STRING"}
• Write a function that will send the message to the process and then immediately wait to receive the response back.
