Example MPI02
-------------

An example of dosimetry in a water phantom.

* Geometry     : water phantom
* Primary      : broad beam (200 MeV proton)
* Physics List : QGSP_BIC
  You need to set an additional environment variable;
  $G4LEVELGAMMADATA indicates a directory path for the data of
  "low energy electromagnetic processes".
* Analysis     : ROOT histogramming
  ROOT should be installed under $ROOTSYS.

- Score dose distribution in a water phantom.
- Learn how to paralleized your applications.
- Create a ROOT file containing histograms/trees in each node.
  * treat multiple outputs properly:
    each slave node generate a ROOT file, whose file name should
    be different from each other.
