15//
16// 2009-01-17  Gregory Soyez  <soyez@fastjet.fr>
17//
18//        * put the code in the fastjet::cdf namespace
19//
20// 2008-08-15  Gavin Salam  <salam@lpthe.jussieu.fr>
21//
22//        * switched JetClu plugin over to proper indexed tracking of
23//          jet contents rather than a (dodgy) map based on particle
24//          energies
25//
26// 2006-09-24  Gavin Salam  <salam@lpthe.jussieu.fr>
27//
28//        * replaced the private m_index variable by a public fjindex
29//          one for tracking within FastJet
30//
31// 2006-09-24  Gavin Salam  <salam@lpthe.jussieu.fr>
32//
33//        * added JetClu+MidPoint to FastJet
