BezierPatch init issue

[jasperSpeicher]

It looks like maybe the second level of arrays in the 2d array also needs to be initialized before they are accessed. otherwise they are undefined.

var BezierPatch = function(points){
this.points = (points === undefined)?[] : points;
for (var i = 0; i < 4; i++) {
for (var j = 0; j < 4; j++) {
this.points[i][j] = new Vec3D();
}
}
};

thank you for bringing this to my attention. I have fixed the issue with the constructor as well as another problem with BezierPatch#computePointAt.

I will close this issue once merged into master and released.

thank you!
