This is a MASSIVE update. The better version of the pull request #34 I made earlier.
This pull request adds a new program named "box" (I also made a wiki page for it) and some changes with some text in the programs "Raspberry Pi Detector" and "areas" and changes to the contribution guidelines.
Here is the full list of changed stuff.

Added a page for the "box" program in this pull request.
Changed some text in the program "Areas".
Added a program called "box" Changed text in the program "Raspberry Pi Detector".
Added the "box" programs wiki page to the page index.

So I made this python script to try and detect a Raspberry Pi connected locally on your network. This is kinda useful when your trying to see if you can connect to your Raspberry Pi from your PC. It works by using the OS module to send a Ping Request to raspberrypi.local, The default local IP address for the Raspberry Pi. If the ping request goes through then a message will say there is a pi on your network, if it fails it will say that there is probably no pi on your network.

Tl;Dr I made python script that scans for a Raspberry Pi and tells the user if there is one on their local network or not.

• Python Version [e.g. 3.1]

Additional context Add any other context about the problem here.

Describe the bug The bug occurs when running the program Box. In a online interpreter it appears with missing character symbols and seems to be using a lot of RAM compared to a normal python program. I think it's doing this because it is running out of RAM and breaking. Running it on my PC with the python interpreter works perfectly fine.

To Reproduce Steps to reproduce the behavior:

1. Go to pretty much any online python interpreter
2. Run the Box Program
3. See the missing character symbols

Expected behavior The program will show a Box with some text inside with the box being made out of characters from the Extended Ascii Character Set.
