/**
* This file replacement (for /app/code/core/Mage/Core/Model/App.php) is necessary for an early
* launch of the Extended Rewriter (ER) subsystem developed by AITOC Inc.. The Magento system
* allows only one rewrite to be used by extensions to extend some of the core Magento functionality.
* Often different extensions need to use rewrites of the same class in order to work properly.
* The `one rewrite` restriction leads to the situation when manual changes in extensions' class
* files are required to make extensions work together. Thereby extensions' install and update
* processes become much more complex.
*
* The ER subsystem solves conflicts between AITOCs' and 3rd-party extensions' rewrites by creating
* generic chains of rewrites without making direct changes to the extensions' original class files.
* It makes the process of modules installation easier and prevents many issues which could be caused
* by conflicts of rewrites.
*
* Please note that this file replacement does NOT affect normal work of the Mageno system - it only
* launches an additional subsystem during system initialization. All the extensions developed by AITOC Inc.
* could work without this subsystem but it will be much harder to install them as it may be necessary
* to manually solve rewrites' conflicts with 3rd-party extension. Please note that solving conflicts
* with 3rd-party extensions is out of AITOC's free support policy. The ER subsystem could be disabled
* by removing this file but it is strongly not recommended.
