BRL-CAD has a geometry editor application called MGED that will run in a graphical or text console mode (mged -c)

Your task is to do some exploratory research.  Make it so that we can go to a web page and interact with a remote instance of MGED. Don't worry about making it pretty, we're looking for proof-of-concept.

You can do this task in any language you like, but you need to set up a temporary demo somewhere that we can get to.  Provide the URL and your source file(s).

CAUTION: Keep it protected or run it in a VM or otherwise "sandboxed" environment, however, because MGED does allow shell command execution and we wouldn't want some random individual causing problems. :)
