/**
* A request data store is a component that manages data that is
* linked to the current request.
* With the setRequestData() method you can link any object to the
* current request. This object can be fetched via getRequestData()
* as long as the request is running. This data is not available
* in any sub-request (cocoon: protocol calls).
* If you want to share data between the main request and any sub-request
* than you have to use the setGlobalRequestData etc. methods.
*
* This component is a replacement for the request lifecycle and
* global request lifecycle components.
