/**
* This class is a test case that verifies several properties of the
* GdDocumentList implementation, namely:
* (1) The list uses the last modified property of the contained entries for
* checkpointing, until after the last document, at which time it starts to use
* the given final checkpoint string instead.
* (2) All and only those documents passed to the constructor in a List are
* returned identically, in order, by traversal.
