CChainedCacheDependency represents a list of cache dependencies.
If any of the dependencies reports a dependency change, CChainedCacheDependency will return true for the checking.
To add dependencies to CChainedCacheDependency, use Dependencies which gives a CTypedList instance and can be used like an array (see CList for more details}).
