com.google.gwt.dev.jjs.impl.JsFunctionClusterer
Re-orders function declarations according to a given metric and clustering algorithm in order to boost gzip/deflation compression efficiency. This version uses the edit-distance algorithm as a metric, and a semi-greedy strategy for grouping functions together.
