Web interface

[Idrian]

A web interface for the GitHub hosted page to demonstrate the voxelc.js library or to allow people to quickly use it as is.

The header image says voxel.js, which is the name of another library. Maybe it should rather be voxc.js or Voxel Converter Library?

w3.css can make it easier to style the website and make it responsive:
