class AliITSv11GeometrySDD: public AliITSv11Geometry

 Standard constructor

 Constructor setting debugging level

     Copy Constructor
 do only a "shallow copy" ...

 Look like a destructor
 Smell like a destructor
 And actually is the destructor

 Define display colors and the non constant geometry parameters

 Called to get a medium, checks that it exists.
 If not, prints an error and returns 0

 Get the actual number of ladder in layer 3

 Get the actual number of ladder in layer 4

 Create basics objets which will be assembled together
 in Layer3 and Layer4 functions

 a debugging function for checking some possible overlaps

 Add a dx,dy,dz translation to the initial TGeoCombiTrans

 for code developpment and debugging purposes

 Insert the layer 3 in the mother volume. This is a virtual volume
 containing ladders of layer 3 and the supporting rings

 Insert the end-ladder of layer 3 in the mother volume.
 (cooling, Carlos, LV, HV ...)

 Insert the layer 4 in the mother volume. This is a virtual volume
 containing ladders of layer 4 and the supporting rings

 Insert the end-ladder of layer 4 in the mother volume.
 (cooling, Carlos, LV, HV ...)

 return an assembly volume containing the CF ladder

 Create one half of the V shape corner of CF ladder

 return a box containing the front-end hybrid

 Return a TGeoVolume* containing a segment of a ladder.

 Create a pine support and its pine
 axis of rotation is the cone axis, center in its middle

 Create half of the cooling pipe support (ALR-0752/3)

Create half of the cooling pipe support (ALR-0752/3)

 based on ALR 0752/8

 Return an assembly containing a end of a CF ladder.

 return an assembly containing the CARLOS end-ladder board
 and the heat bridge

 Creates the assemblies containing the LV cards (left and right)

 return an assembly containing the HV card

 return an assembly containing the LV, HV and Carlos cards of one ladder
 and their cooling system

 return an Pcon containing the LV, HV and Carlos cards of one ladder
 and their cooling system
 This is the code actually used for the end ladder cards

 return an assembly of the support rings, attaching the ladders to the cone

 return a box containing the SDD sensor

 return a box volume containing the detectors

 return a box volume containing the detectors
 Special case for Layer 3 Ladder 2 which is rotated (cannot simply
 rotate the standard volume, because the module numbering would be wrong)

 Creates a cone along z where the section is approximately constant
 with z. This is for simulation of cables, because a cone with a constant
 radius difference would show a quantity of matter increasing with z...
 The max radius of the created Pcon is evolving linearly, the min radius
 is calculated at several steps (nDiv).
 z2 > z1 (required by the Pcon)

 just a helping function

 Create some cables portions from SDD modules grouped
 and attached at the border of the SSD cone

 Creates and inserts the SDD cables running on SDD and SSD cones

 Input:
         moth : the TGeoVolume owing the volume structure

 Functions for coding, testing, debugging

 Create a TGeoCombiTrans: general rotation in phi and (dy,dz) translation
