Detailed Description

Handles signals related to document file actions. The file action signals it receives are dictated by the PstLstDocServiceProvider class.

PstLstDocResponder implements IResponder based on the partial implementation CResponder.

We are interested in knowing when a documnet is opened or closed. When these events happen, we have to attach/detach a document observer which will get notified when a document's hierarchy is changed. This allows us to purge the custom data associated with the page item. In PstLstDocServiceProvider, we registered our interests in kAfterNewDocSignalResponderService, kDuringOpenDocSignalResponderService, and kBeforeCloseDocSignalResponderService, that will allow us being notified when these event occurs. In that case we will attach/detach the document observer accordingly.
