Work on VecGeom Benchmark program

Abstract : GEANT-4 is s particle-material interaction simulator used in various fields. Now GEANT-V project is ongoing to replace GEANT-4 in the future due to the paradigm change at computer architecture. Core clock already reaches at the threshold of its limit; hence it is hard to handle scalar parameter faster than now on. For this reason GEANT-V use vector parameters can handle faster with certain CPU compilers and CUDA. VecGeom is the geometry library which will be used at GEANT-V. A benchmark program for VecGeom is to verify if VecGeom is faster than other geometry libraries in ROOT or GEANT-4. XRayBenchmark for VecGeom provides a good way to verify if VecGeom is faster than other geometry libraries in ROOT or GEANT-4. While performing this task I found a bug at DistToCone function in TGeoCone, ROOT6.
