> TopDocCollector's members and constructor are declared either private or
> package visible. It makes it hard to extend it as if you want to extend it
> you can reuse its *hq* and *totatlHits* members, but need to define your own.
> It also forces you to override getTotalHits() and topDocs().
> By changing its members and constructor (the one that accepts a PQ) to
> protected, we allow users to extend it in order to get a different view of
> 'top docs' (like TopFieldCollector does), but still enjoy its getTotalHits()
> and topDocs() method implementations.
