   * Do we use Apache Commons (e.g. Validate)?
   * How many Similarities of a type? With Stats we definitely need to answer this.
   * Also order of calls is always: computeStats(field1) -> *DocScorer(field1) -> computeStats(field2) ...?
+  * sumOfSquaredWeights: a weighted squared average, but why include idf (the "weight", in both meanings)? What about similarities that have no idfs?
  
  === TODOs ===
   * idf is used outside of Similarity in MultiPhraseWeight, PhraseWeight, SpanWeight, TermWeight
