Data upload feature

[GenevieveBuckley]

Currently there's not a super easy way for users to load their data for microscopium.

At some point, there probably needs to be a data upload feature built - without one it'll be pretty hard to get new users past the intial hurdle and on board. I've recently been doing some user testing for the CAVE's PREVIS data upload tool, and I'm wondering if there might be some lessons we can draw from it.

PREVIS details:

Platforms: Linux, MacOS
Built with: Node.js, python, potree, sharevol, ThreeJS, Angular5, Firebase

I don't see a repository for this on either Toan's Github or the MIVP Github page - it might be best just to email Toan directly if we want to know more about it.
