Three FSD geometries which are consistent with current beampipes design following same energies.

This is Block STS variant v22d. Aditionally it has Cooling pipes, LV cables(Sumida cables), HV cables(Habia cables),
Optical fibre cable box, Power cable box(LV and HV cables), cooling tubes(Perforated tubes) along to the central ladders.

magnet_v22b has top volume redefined as an assembly. Magnet materials
are defined with explicit tag. Materials are defined in gdml script
to make correct radlen and intlen declaration in case future material
budget maps need to be generated.

New media.geo used in the generation of beampipes v21e and v21f

v21f has no deflection i.e. no magnetic field
v21e has maximum deflection i.e. Gold 2AGeV

Fixes the weight atomic number discrepancy

New definition of the carbon fiber

Inserts materials int the root binary

Includes proper material definitions in both binaries

Corrects the names of the top volumes in both binaries

newly generated binaries to resolve radiation lenght discrepancy

Resolves the naming convention discrepancy

New binaries for downstream beampipe 21e (max deflection), 21f (no deflection), 21g (3.3AGeV), 21h (12AGeV) without internal overlaps

Adds new versions of 21e and 21f files (forgoten in previous commit)

Macros for beampipe geometry creation with VolumeAssembly used to avoid keep volumes
Part of the which is supposed to be inside STS back wall is missing due to an unexplanable overlaps. The origin is not affected.
 create_bpipe_geometry_v21e.C - maximum deflection 2.5 deg
 create_bpipe_geometry_v21f.C - no magnetic field
 create_bpipe_geometry_v21g.C - Au+Au 3.3 AGeV/c, 50% MF
 create_bpipe_geometry_v21h.C - Au+Au 12 AGeV/c, 100% MF

Removal of the binaries pipe_v21e.geo.root, pipe_v21f.geo.root,pipe_v21g.geo.root, and pipe_v21h.geo.root picked up on  unknown place, possibly some old commit

Based upon mvd_v20c_tr
mvd_v20f has first station removed,
mvd_v20g has first two stations removed,
The top and bottom plate are also removed.

Added a missing HexPly material in media.geo.
updated sis18_electron to use mvd_v20g_tr, added back magnet geometry

Includes media.geo with BP material definiations.

STS v21h: The geometry has the target positioned at -4 cm. It can be used with the beampipe 40mm diameter upstream side
          and 104mm diameter downstream side. It has a beampipe flange on the back-side of the STS wall.

          In addition, the geometry has a sensor thickness 320 um which is similar thickness of the real silicon sensors purchased from the Hamamatsu Photonics
          for the use in the real experiment.

          Furthermore,the mico-cable is defined as a single volume attached to the silicon sensors. Micro-cable thickness (320 um) is choosen and
          the material Manganese is taken based on the calculation done based on the current microcable design, thickness and its material.
          The material is defined as STS_Manganese in the media.geo file.

STS v21i: The geometry has the target positioned at -44 cm from the center of the magnet. It can be used with the beampipe 40mm diameter upstream side
          and 104mm diameter downstream side. It doesn't have a beam-pipe flange on the back-side of the wall.

          In addition, the geometry has a sensor thickness 320 um which is similar thickness of the real silicon sensors purchased from the Hamamatsu >
          for the use in the real experiment.

          Furthermore,the mico-cable is defined as a single volume attached to the silicon sensors. Micro-cable thickness (320 um) is choosen and

          The material is defined as STS_Manganese in the media.geo file.

updated binaries files and media.geo file with a material name STS_Cable_21

v21f: STS geometry is similar to the version v21b. The target position considered from -4 cm.
The geometry can be used with the beampipe with diameter 40 mm upstream side and 104 mm downstream side.
The geometry has beampipe flange on the back-side of the wall.

v21g: STS geometry is similar to the version v21e. The target position is at -44 cm considering global origin
from the center of magnet. The STS local coordinate is from the last station.

In both geometry, the STS box and the beam pipe flange is made of Carbon fiber: The material has 70% carbon fiber with
density 1.75 g/cm3 and epoxy resin (30%) with density 1.2 g/cm3. The material is defined in media.geo file as
STS_CarbonFiber_21.

Variants:

* v20a: stations at old location but all changes reported below in
* v20b: as v20a, but TPG carrier thickness increased to
  500 µm, all stations moved upstream by 4cm.
* v20c: as v20a but moved upstream by 4cm.

Detailed changes in those new geometries are:

* Position of the MVD moved 4cm upstream (v20b & v20c),
* TPG carriers' thickness updated (from 300 µm in v17 to 380 µm [500 µm]),
* MVD specifc custom materials defined in media.geo (TPG, diamond, glue, fpc),
* CVD diamond only used for first station on VX version,
* transformation matrix added to the ROOT output file
  placing the detector in the CBM coordinate system,
* addition of a top and bottom mounting plate of 10mm aluminium,
* vertical aluminium heatsinks' thickness increased by 3mm to mock
  the expected material from FEBs that will be mounted on top of them.
