Launch a local live server to test web based apps locally (eg XMLHttpRequest)
## Make sure `node.js` is installed. Navigate to folder containing index.html doc you want to test.
npm install -g live-server
# This installs it globally so it can be accessed from anywhere. Then, again in the same folder run:
live-server
# This opens app in browser through port 8080. If you open console, JavaScript server based functionality should now be working.
