// History:
|
|
// 02 Dec. 1995, G.Cosmo : Structure created based on object model
|
|
// 15 Feb. 1996, K.Amako : Implemented the 1st version
|
|
// 01 Jul. 1996, K.Amako : Hidden bin from the user introduced
|
|
// 26 Sep. 1996, K.Amako : Constructor with only 'bin size' added
|
|
// 11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector
|
|
// 9 Mar. 2001, H.Kurashige : add PhysicsVector type and Retrieve
|
