By default DomSnapshot configured to use demo firebase api to manage snapshots

	const snapshot = new DomSnapshot();
	// waiting for firebase initialization
	snapshot.loaded().then(()=>{
	        // saving current DOM as snapshot
		const id = snapshot.saveSnapshot();
		console.log('snapshotId', id);
		setTimeout(() => {
			console.log('restoring current snapshot');
			snapshot.showSnapshot(id)
		}, 3000);
	});

"Offline" usage example (without firebase sync)

	
	var selector  = '#readme > article > pre';

	var s1 = snapshoter.takeSnapshot(selector);

	document.querySelector(selector).style['fontSize'] = '20px';
	document.querySelector(selector).setAttribute('foo', 'bar');
	var s2 = snapshoter.takeSnapshot(selector);

	var diff = snapshoter.getSnapshotsDiff(s1, s2);

	console.log(diff);

	// capture node and send it to server
	snapshoter.saveSnapshot(Date.now(), snapshoter.createSnapshot('body'))
