Detailed Description

DD4hep detector-element plugin: single solid from a STEP file.

Compact XML usage:

<detector id="1" name="MyBeamPipe" type="G4OCCT_STEPSolid" vis="BlueVis">
  <step_file path="geometry/beampipe.step"/>
  <position x="0" y="0" z="0"/>
  <rotation x="0" y="0" z="0"/>
  <material name="Aluminium"/>
</detector>

The implementation constructs a TGeoOCCTSolid directly from STEP. This keeps DD4hep/ROOT geometry and navigation on the exact shared G4OCCT query kernel instead of a tessellated approximation.
