title: What is ContiguousPagedList?
body: <p>I was looking into <code>Android Paging</code>, and there seems to be a Concrete imprementation of <code>PagedList</code> as  <code>ContiguousPagedList</code>. <strong>What's the use of this class?</strong> Looked to find it's usage / reason for existence but didn't find any. Can anyone explain why this <code>ContiguousPagedList</code> exists? </p>
