PHP experiments showing spl_autoload_register() and require_once successfully and failing to resolve circular dependencies

To Execute and Generate the Fatal:

php run.php

Three ways to "fix" the fatal

1. animal.php should not require_once('cat.php'): This commit
2. Animal class should not extend Creature class: This commit
3. Instead of using autoloader, explicitly require_once creature.php and animal.php from run.php: This commit
