Installing Visual Studio Code on linux - non-root user

Based on a stack overflow answer:

1. Download Visual Studio Code for Linux
2. Copy it somewhere you are happy to extract it into and keep eg ~/bin
3. Extract it: tar -xvf VSCode-linux-x64.tar.gz
4. Add the executable to the system path eg export PATH=$HOME/bin/VSCode-linux-x64
5. Run the code executable to open Visual Studio Code
6. (Optional) add the export statement into your ~/.bashrc
