* This task involves building UML diagrams for the calculator.
****Wiring Diagram*** This diagram demonstrates how the calculator is wired up.
****UML Class Diagram*** We are taking a websocket connecting to it and printing the packet all it one. This take doesnt require us todo much else with the packet so it can just be called in a function. 
****send_packet(websocket, sourcePort, deskPort, payLoad)*** To send packets to the server they need to be in UDP format in base64. This function will create a header for the payload including the correct checksum so the server can confirm the packet has arrived valid. 
****unittest.py*** unittest is an inbuilt Python library. Its a test runner and is specially design for running tests and debugging. This one contains a few useful tools that we are going to use. It works similarly to the assert function. Task 3 doesn't have any output other than to the terminal. I could alter the output but this is out of my scope for the project. Here I am just checking if the program runs correctly. All the tests were successful.
