This is almost identical to an [page:Object3D Object3D]. Its purpose is to make working with groups of objects syntactically clearer.
		var geometry = new THREE.BoxBufferGeometry( 1, 1, 1 );
		var material = new THREE.MeshBasicMaterial( {color: 0x00ff00} );
		var cubeA = new THREE.Mesh( geometry, material );
		cubeA.position.set( 100, 100, 0 );
		var cubeB = new THREE.Mesh( geometry, material );
		cubeB.position.set( -100, -100, 0 );
		//create a group and add the two cubes
		//These cubes can now be rotated / scaled etc as a group
		var group = new THREE.Group();
		group.add( cubeA );
		group.add( cubeB );
		scene.add( group );

A string 'Group'. This should not be changed.
