Geant4 tutorial exercises

The directory structure of your simulation area, $HOME/tutorial in this case, should be as follows:

 GNUmakefile : where appear the name of the executable, 
               in this case myMain;
 
 include/ : where all the header files (.hh, .h, .icc) stay;

 src/ : where all the corresponding source or implementation
        files (.cc) stay.

After you have setup your environmental variables, to build the executable type:

     
                        gmake

which produces the executable (myMain) in: $G4WORKDIR/bin/$G4SYSTEM.
Suppose that your PATH includes $G4WORKDIR/bin/$G4SYSTEM you can execute it by simply typing its name, myMain.
You have two possibilities:

myMain macro.g4 to run in batch;
myMain to run interactively,

Other files or subdirectories can be added if you want. In this case, the training subdirectory contains the exercises and their solutions.

NB - At the very beginning, you will not find GNUmakefile, and the directories include and src. It is the purpose of the 0_start/ exercise to provide it, and to fill properly the directories include and src. See below.

Here how to use training directory is organized.

training has two subdirectories:

exercises - where you find the test of the exercises, as ToDo.txt files;
solutions - where you find the files that should be created/modified in order to solve the exercises. subdirectory structure of exercises and solutions is exactly the same.
In order to use a solution to a given exercises, for example 0_start, you have to do the following:
1. copy the *.hh files that are in:
  tutorial/training/solutions/0_start
  into: tutorial/include
2. copy the *.cc files, excluded myMain.cc, that are in:
  tutorial/training/solutions/0_start
  into: tutorial/src
3. copy all other files (myMain.cc, GNUmakefile, macro files *.g4 ) that are in:
  tutorial/training/solutions/0_start
  into: tutorial
NB - For Windows only: in the analysis exercises ( 10_analysis , 10b , 10c ) you should use JAS as analysis tool rather than Anaphe: this means, in practice, that you have to move any file which ends with the string -win32-Jas to a file with the same name without such string, for example:
```
       cd tutorial/solutions/10_analysis/
       mv GNUmakefile-win32-Jas GNUmakefile
       mv MyAnalysis.cc-win32-Jas MyAnalysis.cc          
```
