Embedding Oppia explorations in the OpenEdX platform

Oppia is a tool for creating short interactive tutorials (called 'explorations') that try to simulate a conversation with a human tutor. This XBlock allows Oppia explorations to be embedded in OpenEdX courses.

For installation instructions, please consult the latest OpenEdX documentation. You may also find this tutorial useful.

Notes:

1. You will need to add the value "oppia" to the advanced_modules field in Studio's 'Advanced Settings' menu.
2. On devstack, the XBlock does not show up in Studio as a live preview in the editor. However, it does show up in the LMS.
3. This XBlock also comes with default logging capabilities that make use of edX's event-tracking library (documented here).
4. This XBlock does not support translations out-of-the-box. For an example of how translations could be implemented, please see this fork.
