23.2.2010 Kamil Sedlak

Browse Source 
Several things were added in this version:
  1) varibale save_time() has been added to the root output tree
  2) possibility to read in field maps, in which varibles x,y,z
     increase differently than previously expected
     (see the description of "variableIncreasingOrder" in the
      "3DEOpera" paragraph of the documentation).
  3) Added "3DEOpera" format of the fieldmap
  4) Added file G4EqEMFieldWithSpin.cc_for_Geant4.9.2p02_only  that
     should be used only in the Geant version 4.9.2p02 (there was
     a bug in this file, which is not present for any other version of Geant4) 
  5) Examples 101.mac and 102.mac added, but its description has not
     been completed yet in the musrSim.pdf.

\section{Example 1 -- Electrons passing through two scintillator tiles (101.mac)}
One of the easiest example to illustrate the basic features of the musrSim (and/or Geant4) is to
shoot electrons into a scintillator block, and to observe the energy deposited inside it.

illustrates a simple geometry made of an electron source and two blocks
of scintilator tiles with the dimensions of $3 \times 3 \times 2\,$mm,
which is defined in the macro file ``101.mac''.
