  <comment> Simplified All Silicon Tracker based on:
    https://github.com/reynier0611/g4lblvtx/blob/master/macros/auxiliary_studies/simplified_geometry/Fun4All_G4_simplified_v2.C
    With some added info on ITS3 chip from
    https://indico.bnl.gov/event/10677/contributions/45591/attachments/33204/53254/20210318-IR2%40EIC-SVT.pdf
    To be used as standin until we get more detailed specs from the working group on the tracker.
    Note that most details are replaced with 

    Note: initial implementation with hard-coded values,
          TODO: add parametrization
