 Generate the list of Trd1 modules
 which will make up the EMCAL
 geometry
 key: look to the AliEMCALShishKebabTrd1Module::

This method was too long to be
included in the header file - the
rule checker complained about it's
length, so we move it here.  It returns the
shishkebabmodule at a given eta index point.

Print information from geometry

 Tells if a particle enters EMCAL

 calculates the impact coordinates on EMCAL (centre of a tower/not on EMCAL surface)
 of a neutral particle
 emitted in the vertex vtx[3] with direction theta and phi in the ALICE global coordinate system

 Checks whether point is inside the EMCal volume

 Checks whether point is inside the DCal volume

 Checks whether point is inside the EMCal volume (included DCal), used in AliEMCALv*.cxx

 Code uses cylindrical approximation made of inner radius (for speed)

 Points behind EMCAl/DCal, i.e. R > outer radius, but eta, phi in acceptance
 are considered to inside

Provides shift-rotation matrix for EMCAL

 This method transforms the (eta,phi) index of module in a
 TRU matrix into Super Module (eta,phi) index.

Transform clusters cell position into global with alternative method, taking into account the depth calculation.
Input are: the tower indeces,
           supermodule,
           particle type (photon 0, electron 1, hadron 2 )
           misalignment shifts to global position in case of need.
