Minimal version PHP: 5.2.1
In some cases (for some backend) need memcache


Comment language: Russian
========================================
	*	Motivation

Create simple and powerful caching module with clear logic. To work on a single server, but at the same time, the highloaded project. 
With the ability to change the strategy of cashing in on the current load level of the project.

	*	Architecture

The main logical units are:
    * Cacher - front to caching classes.
    * Cacher_Backend - actually own caching classes.
    * Slots - caching and access to the cache via the slots.
    * Tags - to simplify the management of cache, and mainly for recaching.
    * Types of caching - for transparent caching strategy changes. Ie specific caching backend, via the slot (or tag), which in turn operate types. 

	*	Using

class Cacher
Requires a class inherits an interface Cacher_Backend - a family of classes that implement the backend class Cacher 
All operations with the cache is carried out at a lower level through the backends.
Backend can be a file system, shared memory, memcache, Sqlite, and other cacheing system.


	*	Example:


$slot = Cacher::create('User',$User);

//Get data
if (false === ($CacheData = $slot->get())) { 
       $CacheData = GetFromAnyExternal();
       $slot->addTag(Cacher_Tag::create('SmplTag',  $User));
       $slot->addTag(Cacher_Tag::create('SmplTag1', $User));
       $slot->set($CacheData);
}
 ...
 ...
 If you then need to reset some a tag, you will need to do so: 
 Cacher_Tag::create('AnyTagData', $AnyTagDataObj)->clear() // Clear cache of tag
