> The move away from static objects toward instance variables has resulted in 
> CommonGrams constructor parsing its analysis.common.terms.file for each 
> query. I'm not certain how large a performance impact this really is, but it 
> seems like something you'd want to avoid doing for each query. Perhaps the 
> solution is to keep around an instance of the CommonGrams object itself?
