I raise an issue #462 about creating multiple instances of JSCAD per page and be informed that V2 has the ability to do it. So I clone the V2 repository, start a server on ./web and open the demo.html, but I find no viewers or designs on it(maybe already work?) or what it should look like if it is working properly.

I also find that the demo.js creates two instances of JSCAD using makeJscad(), which is exactly what I want. But I insert some lines of demo.js into demo.html, there are also no viewers or designs. Are there any docs about how to use makeJscad() properly?
