+ ** Creation of STS geometry in ROOT format (TGeo).

+ * 
+ ** v22c: Similar to the geometry version v21e. The STS detector containing 8 tracking stations is decoupled into two-part 
+ *        by introducing a gap of 20 mm, 50 mm and 80 mm.  
+ * 		  The STS is renamed STS-3 and STS-5 where the name defines STS-3 as 3 tracking stations and STS-5 has 5 tracking stations.
+ * 		  In this geometry, STS-3 and STS-5 have a 20 mm gap between them. The pitch (105 mm) between the station within splitted STS geo. (STS-3
+ * 		  and STS-5) remained the same.   
+ ** 
+ ** v21e: Airex foam in the front and  back side wall (Solid).
+ * 		  New beam pipe R = 2.0 cm with thickness 1mm.
+ * 		  Central ladders adjusted 5mm away from the beampipe. Global origin is taken from center of magnet. 
+ * 		  Origin of the STS is taken from last station which is located at(0,0,0) position.	
+ * 		  Global origin is considered from the center of the magnet.
+ *		  Nomenclature for the Halfladders has been changed from the upside(u)	to top (t)
+ * 	      and from downside(d) to bottom (b).
+ **
+ ** v19r: bugfix of v19q - align all halfladders
+ ** v19q: based on v19l - align ladders to virtual plane in station center, closing the gaps in z
+ ** v19p: based on v19k - parameters : delta Z prime = 0.70 cm - delta Z pitch = 0.20 cm
+ ** v19o: based on v19k - parameters : delta Z prime = 0.30 cm - delta Z pitch = 0.20 cm
+ ** v19n: based on v19k - parameters : delta Z prime = 0.50 cm - delta Z pitch = 0.20 cm (bug fix of v19m)
+ ** v19m: based on v19k - parameters : delta Z prime = 0.55 cm - delta Z pitch = 0.20 cm (bug)
+ ** v19l: based on v19k - parameters : delta Z prime = 0.50 cm - delta Z pitch = 0.15 cm
+ ** v19k: ladders on upstream side of units get upper half ladders installed first, 
+ **       ladders on downstream side of units get lower half ladders installed first, 
+ **       this saves 1.5 mm space in z per station, 12 mm in total (LadderType went from 3 to 4 digits)
+ **       parameters : delta Z prime = 1.00 cm - delta Z pitch = 0.15 cm
+ ** v19j: use overlap and distance parameters from CAD model
+ ** v19h: put STS stations from v19d at z-positions = 260; 365; 470; 575; 680; 785; 890; 995 mm
+ ** v19g: place a box with services around v19e
+ ** v19f: place a box with services around v19d
+ ** v19e: increase spacing between stations by +10 mm from 100 mm
+ ** v19d: increase spacing between stations by + 5 mm from 100 mm
+ ** v19c: drop station 8 and increase spacing between remaining 7 stations from 10 cm to 12 c
+ ** v19b: introduce FEB orientation in ladder numbering (LadderType went from 2 to 3 digits)
+ ** v19a: import passive materials from gdml file
+ **       extend CF ladder structures and cables towards FEE plane
+ **       change CF ladder frame shape
+ ** v18d: increases thickness of sensors within a 7.5 degree cone from 300 mu to 400 mu (based on v18b)
+ ** v18c: fixed cut-out windows in cooling plates, improve the box shape/materials
+ ** v18b: increases thickness of sensors within a 7.5 degree cone from 300 mu to 400 mu
+ ** v18a: adds 9 cooling/holding plates and a box around the setup
+ ** v16g: v16g is the new standard geometry from November 2017
+ ** v16g: switch from stations to units - left / right ("Unit01L", "Unit01R")
+ ** v16f: switch from stations to units
+ **     - split in upstream / downstream and left / right parts
+ **     - named Unit0xUR, Unit0xUL, Unit0xDR, Unit0xDL
+ ** v16e: switch from stations to units - upstream / downstream ("Unit01U", "Unit01D")
+ ** v16d: skip keeping volumes of sts and stations
+ ** v16c: like v16b, but senors of ladders beampipe next to beampipe
+ **       shifted closer to the pipe, like in the CAD model
+ ** v16b: like v16a, but yellow sensors removed
+ ** v16a: derived from v15c (no cones), but with sensor types renamed:
+ ** 2 -> 1, 3 -> 2, 4 -> 3, 5 -> 4, 1 -> 5
+ **
+ ** v15c: as v15b without cones
+ ** v15b: introduce modified carbon ladders from v13z
+ ** v15a: with flipped ladder orientation for stations 0,2,4,6 to match CAD design
+ **
+ ** TODO:
+ **
+ ** DONE:
+ ** v15b - use carbon macaroni as ladder support
+ ** v15b - introduce a small gap between lowest sensor and carbon ladder
+ ** v15b - build small cones for the first 2 stations
+ ** v15b - within a station the ladders of adjacent units should not touch eachother - set gkLadderGapZ to 10 mm
+ ** v15b - for all ladders set an even number of ladder elements 
+ ** v15b - z offset of cones to ladders should not be 0.3 by default, but 0.26
+ ** v15b - within a station the ladders should be aligned in z, defined either by the unit or the ladder with most sensors
+ ** v15b - get rid of cone overlap in stations 7 and 8 - done by adapting rHole size
+ **
+ ** The geometry hierarachy is:
+ **
+ ** 1. Sensors  (see function CreateSensors)
+ **    The sensors are the active volumes and the lowest geometry level.
+ **    They are built as TGeoVolumes, shape box, material silicon.
+ **    x size is determined by strip pitch 58 mu and 1024 strips 
+ **    plus guard ring of 1.3 mm at each border -> 6.1992 cm.
+ **    Sensor type 1 is half of that (3.0792 cm).
+ **    y size is determined by strip length (2.2 / 4.2 / 6.3 cm) plus
+ **    guard ring of 1.3 mm at top and bottom -> 2.46 / 4.46 / 6.46 cm.
+ **    z size is a parameter, to be set by gkSensorThickness.
+ **
+ ** 2. Sectors  (see function CreateSectors)
+ **    Sectors consist of several chained sensors. These are arranged
+ **    vertically on top of each other with a gap to be set by
+ **    gkChainGapY. Sectors are constructed as TGeoVolumeAssembly.
+ **    The sectors are auxiliary volumes used for proper placement
+ **    of the sensor(s) in the module. They do not show up in the
+ **    final geometry.
+ **
+ ** 3. Modules (see function ConstructModule)
+ **    A module is a readout unit, consisting of one sensor or
+ **    a chain of sensors (see sector) and a cable.
+ **    The cable extends from the top of the sector vertically to the
+ **    top of the halfladder the module is placed in. The cable and module
+ **    volume thus depend on the vertical position of the sector in 
+ **    the halfladder. The cables consist of silicon with a thickness to be
+ **    set by gkCableThickness.
+ **    Modules are constructed as TGeoVolume, shape box, medium gStsMedium.
+ **    The module construction can be switched off (gkConstructCables)
+ **    to reproduce older geometries.
+ **
+ ** 4. Halfladders (see function ConstructHalfLadder)
+ **    A halfladder is a vertical assembly of several modules. The modules
+ **    are placed vertically such that their sectors overlap by 
+ **    gkSectorOverlapY. They are displaced in z direction to allow for the 
+ **    overlap in y by gkSectorGapZ.
+ **    The horizontal placement of modules in the halfladder can be choosen
+ **    to left aligned or right aligned, which only matters if sensors of
+ **    different x size are involved.
+ **    Halfladders are constructed as TGeoVolumeAssembly.
+ **
+ ** 5. Ladders (see function CreateLadders and ConstructLadder)
+ **    A ladder is a vertical assembly of two halfladders, and is such the
+ **    vertical building block of a station. The second (bottom) half ladder
+ **    is rotated upside down. The vertical arrangement is such that the
+ **    inner sectors of the two halfladders have the overlap gkSectorOverlapY
+ **    (function CreateLadder) or that there is a vertical gap for the beam
+ **    hole (function CreateLadderWithGap).
+ **    Ladders are constructed as TGeoVolumeAssembly.
+ **   
+ ** 6. Stations (see function ConstructStation)
+ **    A station represents one layer of the STS geometry: one measurement
+ **    at (approximately) a given z position. It consist of several ladders
+ **    arranged horizontally to cover the acceptance.
+ **    The ladders are arranged such that there is a horizontal overlap
+ **    between neighbouring ladders (gkLadderOverLapX) and a vertical gap
+ **    to allow for this overlap (gkLadderGapZ). Each second ladder is
+ **    rotated around its y axis to face away from or into the beam.
+ **    Stations are constructed as TGeoVolumes, shape box minus tube (for
+ **    the beam hole), material gStsMedium.
+ **
+ ** 7. STS
+ **    The STS is a volume hosting the entire detectors system. It consists
+ **    of several stations located at different z positions.
+ **    The STS is constructed as TGeoVolume, shape box minus cone (for the
+ **    beam pipe), material gStsMedium. The size of the box is computed to
+ **    enclose all stations.

+
+// Remark: With the proper steering variables, this should exactly reproduce
+// the geometry version v11b of A. Kotynia's described in the ASCII format.
+// The only exception is a minimal difference in the z position of the
+// sectors/sensors. This is because of ladder types 2 and 4 containing the half
+// sensors around the beam hole (stations 1,2 and 3). In v11b, the two ladders
+// covering the beam hole cannot be transformed into each other by rotations,
+// but only by a reflection. This means they are constructionally different.
+// To avoid introducing another two ladder types, the difference in z position
+// was accepted.
+
+
+// Differences to v12:
+// gkChainGap reduced from 1 mm to 0
+// gkCableThickness increased from 100 mum to 200 mum (2 cables per module)
+// gkSectorOverlapY reduced from 3 mm to 2.4 mm
+// New sensor types 05 and 06
+// New sector types 07 and 08
+// Re-definiton of ladders (17 types instead of 8)
+// Re-definiton of station from new ladders

+Summary:
+  This version adds passive materials imported from GDML model to the STS geometry:
+    * Taken from and largely correspond to mechanical CAD drawings of the detector
+    * Thermal insulation box:
+      - made out of carbon sandwitch panel (2mm carbon fiber sheet + layer of carbon foam + 2mm carbon fiber sheet)
+      - front window of complex shape with interface to MVD / target chamber
+      - back window with large aperture (2000 x 1200 mm) square cut into carbon foam
+    * Structural units:
+      - made of 2 complex shape aluminum C-Frames, 15mm thick
+      - placed at 25, 35, ... ,105 cm absolute Z
+      - contain front-end and power distribution boxes with equivalent X_0 values
+
+  Scripted geometry tweaks:
+    * Ladders and cables are extended towards the read-out planes having same lengths in respective rows
+    * Adjusted form and shape of carbon ladder structures from L-type to X-type
+    * Reduced verbosity of this file
+
+  Sensor arrangement is the same as in version v16g
+
+  !! Important for this version is the discrepancy from the mechanical CAD w.r.t. front wall.
+  The square window was replaced by a round one to avoid overlaps with present beam pipe designs, e.g. pipe_v16b_1e
+)";

+STS geometry created with create_stsgeo_v22c.C
+
+Summary:
+  This version adds passive materials imported from GDML model to the STS geometry:
+    * Taken from and largely correspond to mechanical CAD drawings of the detector
+    * Thermal insulation box:
+      - made out of carbon sandwitch panel (2mm carbon fiber sheet + layer of carbon foam + 2mm carbon fiber sheet)
+      - front window of complex shape with interface to MVD / target chamber
+      - back window with large aperture (2000 x 1200 mm) square cut into carbon foam
+    * Structural units:
+      - made of 2 complex shape aluminum C-Frames, 15mm thick
+      - placed at 25, 35, ... ,105 cm absolute Z
+      - contain front-end and power distribution boxes with equivalent X_0 values
+
+  Scripted geometry tweaks:
+    * Ladders and cables are extended towards the read-out planes having same lengths in respective rows
+    * Adjusted form and shape of carbon ladder structures from L-type to X-type
+    * Reduced verbosity of this file
+
+  Sensor arrangement is the same as in version v16g
+
+  !! Important for this version is the discrepancy from the mechanical CAD w.r.t. front wall.
+  The square window was replaced by a round one to avoid overlaps with present beam pipe designs, e.g. pipe_v16b_1e
+
+Global variables: 
+Sensor thickness = 0.03 cm
+Vertical gap in sensor chain = 0 cm
+Vertical overlap of sensors = 0.46 cm
+Gap in z between neighbour sensors = 0.12 cm
+Horizontal overlap of sensors = 0.25 cm
+Gap in z between neighbour ladders = 0.35 cm
+Cable thickness = 0.02 cm
+
+Beam pipe: R1 = 2 cm at z = 18 cm
+Beam pipe: R2 = 5 cm at z = 125 cm
