Basic Usage

<?php

$array = ['foo' => 'bar', 'baz' => 'qux'];
$snapshot = new ArraySnapshot($array); // Totem\Snapshot\ArraySnapshot

$array['foo'] = 'fubar';
$set = $snapshot->diff(new ArraySnapshot($array)); // Totem\Set

var_dump($set->hasChanged('foo'),
         $set->getChange('foo')->getOld(),
         $set->getChange('foo')->getNew(),
         $set->hasChanged('bar'));
