#014685: Small error in Cache-Turorial

In the cache tutorial a small error has crept in:

http://ezcomponents.org/docs/api/trunk/introduction_Cache.html#stacks-and-ezccachemanager

there is a sample which describes how to use a custom configuration for the stack-cache.

at line 5 the code looks like: class myCustomConfigurator extends ezcCacheStackConfigurator

since ezcCacheStackConfigurator is an interface it has to be implemented, not extended.
