Gabriele:

• Restricted computing of vertex function to beam line V(0,0,z)
• Substituted gaussian distribution with capped polynomial -x² + 1 (thanks Christian)
• Reduced bins in voxelisation
• Added extra conf params for better tracking
• Now runtime of vertex function computation is similar to old vertexer!

Some results (in red true vertex of that ROF)

Next steps

• Implement the logic to select vertex candidates, track candidates and fit the vertices
• Tune parameters of the functions
• Test CPU performances
• If comparable with old vertexer, proceed with GPU implementation
