This example demonstrating usage 'gflash' shower parameterisation
in homogeneous calorimeter. Compare with glash1,2,3 the histograms
have been added in this example. This makes it possible to use this
example for fine tuning of GFLASH parameters.
This example allow compare the shower profiles from fast simulation
This example allows to compare the shower profiles from fast simulation
with full simulation by histograming of longitudinal (slice)
and radial profiles with different "binning".
Then GFlash fast simulation can be "tuned" via modification

HIT SCORING
-----------
The virtual cylinder sliced longitudinally (slice) and radially (ring) was used.
The size of the slices and rings are expressed in radiation
length units and can be changed.
eg: /exgflash/det/setLbin 20 1. ---> 20 slices of 1. radl
/exgflash/det/setRbin 5 0.25 ---> 5 rings of 0.25 radl
length units and Moliere radius (Rm) units for rings. The number
of division and division size in fraction of units and can be changed.
e.g.: /exgflash/det/setLbin 20 1. ---> 20 slices of 1. radl
/exgflash/det/setRbin 5 0.25 ---> 5 rings of 0.25 Rm
(MaxBin = 500 in both directions)
In ExGflashEventAction class the arrays corresponded slices and rings was
created and filled with hists information. This arrays was use to fill

histograms later.

The macros to run in batch mode:
test.mac - default macro for example testing
test.mac - default macro for example testing, it show how to use different application commands: redefine the histograms and profiles, change the geometry and material, etc
run01.mac - show how redefine the histograms
csi.mac - like test.mac but produce profiles in CsI Material
csi1.mac - macro which produce profiles in CsI Material
testLong.mac - make the runs with more statistics using default geometry and histograms setting, the material is G4_PbWO4
test0.mac - profile comparison, long run without GFLASH
test1.mac - profile comparison, long run with GFLASH on
csiLong.mac - show how to run testLong.mac with different material (CsI)
Each macro executes two runs with fast simulation flag ON (the output file
name is set to gflash01.root ) and OFF (the output file name is set to gflash00.root )
In addition, the ROOT macros cmpL.C, cmpR.C and cmpE.C file are provided,
which can be used to draw superimposed full and fast histograms for radial
and lateral profiles and also the normalized total energy deposition
in calorimeter.
