Clear out current splat before loading new splat

[healermagnus]

If I dynamically change the src value of an a-entity, I can get it to load new geometry. I added a setSource() method for this.

But I can't seem to see how to clear out the old geometry...?

/*
//where source is:
{
    "a": {
       position: [0,0,0],
       rotation: [0,90,0],
       scale:     [1,1,1],
       src: "some/url/to/file.splat"
    },
    "b": {
       position: [0,0,10],
       rotation: [0,0,90],
       scale:     [2,2,2],
       src: "some/url/to/other.splat"
    },
}
*/
	setSource: function(source) {

		this.el.object3D.position.set(...source.position);
		this.el.object3D.rotation.set(...source.rotation);
		this.el.object3D.scale.set(   ...source.scale);

		this.clearData();
		this.loadData(this.camera, this.object, this.renderer, source.src);
	},

	clearData: function() {
		//...?
	},
