	General purpose function that does all summary computation as well as passage marking.
virtual void	scorePassages (const string &qInfo)
	Score ALL passages currently in this summarizer, optionally given query terms.
virtual void	markPassages (int optLen, const string &qInfo)
	Flag optLen passages for inclusion in summary.
virtual void	addPassage (Passage &psg)

Detailed Description

A simple summarizer implementation that uses sentence selection to create summaries. This example shows how a simple summarizer may look, and how to use the Summarizer abstract with the Passage abstract. Note that this implementation is paired with an implementation of Passage called BasicPassage.
