> SpanFirstQuery and SpanPositionRangeQuery (SpanFirst is just a special case 
> of this), are currently inefficient.
> Take this worst case example: SpanFirstQuery("the").
> Currently the code reads all the positions for the term "the".
> But when enumerating spans, once we have passed the allowable range we should 
> move on to the next document (skipTo)
