STS geometry created with create_stsgeo_v20a.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 = 0.27 cm
Gap in z between neighbour sensors = 0.02 cm
Horizontal overlap of sensors = 0.3 cm
Gap in z between neighbour ladders = 1 cm
Cable thickness = 0.02 cm

Beam pipe: R1 = 1.8 cm at z = 22 cm
Beam pipe: R2 = 1.8 cm at z = 50 cm
Beam pipe: R3 = 5.5 cm at z = 125 cm
