zend-hydrator requires package zend-servicemanager

[Danack]

The dependency on zend-servicemanager is listed under 'dev dependencies' in the composer file.

However the HydratorPluginManager class extends a class from that package, and so gives the error:

Class 'Zend\ServiceManager\AbstractPluginManager' not found

If you attempt to use it without also having the service manager installed.

hmm - apparently the docs at http://framework.zend.com/manual/current/en/modules/zend.stdlib.hydrator.html need updating also.

Doing new Zend\Hydrator\HydratorPluginManager now gives an error:

Zend\ServiceManager\AbstractPluginManager::__construct now expects a Interop\Container\ContainerInterface instance representing the parent container; please update your code

the doc you pointed is for zf 2.4 which not using zend-hydrator ( use zend\stdlib\hydrator ) instead.
