First dirty commit: work in progress

Not yet suitable for anyone’s eyes
Latest state

Still a total mess. Don’t even read these messages until I say so.
Fast marching cubes

Uses web workers and buffergeometry in threejs. This is satisfyingly
fast, but has only been tested in Chrome. Not using transferrable
objects, just structured cloning, so it should be compatible with
everything?? (Need to check.)

Needs some clean up. Will do this soon.
Added VectorModel, fixed THREE.ArrowHelper
Reattached the cameraControls to renderer

Changing it to the container seems to cause bad behavior wrt click
events.
Updated README.md to better document the project
Fixed lecture 2, tweaked VectorModel and MathScene

MathScene renderer clear color is now 0x111111. Not sure about that.
VectorModel now uses a nicer material on the cone.
Merge branch 'master' into gh-pages
