Small example of using the STACK API

This code is based on a modification by Sam Fearn of some of the STACK API code from https://github.com/maths/moodle-qtype_stack

Setup

1. Run docker-compose up
2. Navigate to http://localhost:8080/

Note: The Example question page that ships with the STACK API is found at http://localhost:3080/stack.php

Remark: In docker-compose.xml, the line

    volumes:
      - ./web:/usr/share/nginx/html

is a setting to ease development. It serves the purpose so we don't have to restart the container each time we make any changes content in the web folder.
