-- 1.1.0: New version incorporates optimized code from David Krohn. This should be faster than the old version, with same results if min_r = 0 and preclustering is turned off.
-- 1.0.0: New release using FastJet contrib framework. All of the code has been merged into the VariableR.hh and VariableR.cc files (whereas previously there were separate files for AKT, CA, and the CoreJetAlgorithm classes). The example program runs both AKTVR and CAVR.
