#126 Stopword Removal During Indexing

[Lemur Project]

One should have the option of building an index without stopwords. Currently, one eliminates stopwords at query time if so desired. However, perhaps for space limitation or just the "purity" of an index (index collection statistics not skewed by the presence of useless terms), an index without stopwords may be desireable.

Current query configuration parameters for stopwords and stop structures should be respected at indexing time as well.
