GDML Files for TRD support and macro to convert GDML to ROOT file

See merge request !1

converted from fsd_v23e using GDML export in root.

explicit definition of magnet material in the gdml script. Important in
case material budget maps are made of sections involving magnets in the
future. Correlated to media.geo in geometry repo.

To prevent overlaps, magnets volumes are swapped with assemblies.

Magnet_v22b is a copy of magnet_v22a. The screen (clamps) are removed
from the positioning inside the final assembly. The tag names are
updated.

Record of some changes kept in comments, they are now removed.

Renames to the v22a geometry tag and removes 40cm shift.

Made Yoke_leg box and tap 30 mm longer.

Shifted Yoke hbeam box and trap up and down by 15mm.

Shifted Yoke cylinder and Colils layers up and down by 15mm.

The clamps Yoke_screen_part1 and part2 are increased in length by 30cm

Top and bottom trapezoid and plank are increased in lenght by 30cm.

The Yoke leg trap and Yoke leg box are shifted by +- 15cm

To start modification

This is the vaccum box which connects to the STS box and houses the MVD.

Design is cropped from Mehul's passive sts gdml.

Corrected typo going from diameters to raduis. Forgot to half.

Now shell and full filenames are used.

Combines the v21a target and its shell in a single geometry.

Supplied gdml script would not import into root.

Missing material definitions.

Assemlbies rewritten as volume.

Add top volume defined.

Add world solid

Patrick supplied Target Holder

A segment target which is being used for testing.

Changes the pipe angle as specified

Root default units are in cm whilst GEANT4 are in mm.

For unknown reasons, issue appeared whereby these caused issues when
converting gdml to root geometry.

has a 40.1cm radius cylindical target box of length 28cm with a 5mm
thickness wall. It is front face is 5cm upstream from the target.

Targetbox is intergrated into the upstream beam pipe section.

Downstream beam pipe section is a hollow aluminum tube.

Should remove assemblies as this may not work with Fluka.

versioning control.

Places T0Counter back to its origin.

Inserts the shift as a constant

Adds vacuum material

gdml generated from modified root macro

The Halo or Tail detector is similar to the T0 Counter. It consists of 4 counters placed in a plus symbol.

This is only intended to be the correct material buget.

It contains a five 10mm x 10mm layers One layer of diamond with thickness 80 microns, two layer of gold at 150 nm thick and two layers of chromium at 50nm thick.

adds default beam pipe geometry used in conjunction with the MUCH

Warning, made of lead.
