Support for JupyterLite

This version works on JupyterLite and also removes dependence on setuptools.

Bug fix release

Fix some missing "var" in Javascript and use separate display(HTML()) and display(Javascript()) for some non-Jupyter applications

Option to preserve student responses (fixes broken link)

This is identical to v2.0 but fixes a broken link in the README

Option to preserve student responses

Please read the Readme carefully if you are interested in preserving student responses (for them to submit in their notebook to you). See https:/jmshea/jupyterquiz/blob/main/preserve-responses.ipynb for an example.

Add MathJax 3.x compatibility

Make compatible with MathJax 3.x

Had to update way that dynamic content retriggers rendering by MathJax. Handling asynchronous loading of MathJax is complicated and current approach just waits 0.5 s for MathJax to finish loading if it is not ready when the questions are displayed. May not be enough on all systems.

Better security, hiding example

Improve security of decoding JSON question data.

Much more detailed example/instructions for hiding question/answer data in HideQuiz.ipynb

Hide answers when embedding in Jupyter Notebooks

Supports embedding questions in Jupyter Notebooks with question source data (especially the answers) are hidden from users.

Fixed math output in feedback for numerical questions

This version fixes a bug where LaTeX in the feedback for numerical questions would not be properly typeset. It should work now.

Improved math handling and animated button colors

Improved handling of LaTeX math input as $ $ for inline math or $$ $$ for display math. Animation for color changes on multiple-choice buttons.

Fix MathJax question rendering

Make MathJax re-typeset the page when questions are loaded, too.
