/*
  StiDetPolygon is derived from StiPolygon and is meant to represent an easily navigable geometrical
  representation of a generic "cylindrical" collider detector.  That is, it preserves the genreal cylindrical
  symmetry of the detector while allowing for detector planes assembled in polygons.  Navigation is meant
  to preceed by stepping from one polygon to the other.

  Each polygon has n-sides, and each side will hold a pointer to a detector object.  Therefore, navigation
  can proceed without any information about the detector itself

  BEWARE!!! StiDetPolygon is derived from a concrete base class (generally this is a poor design), so don't push it too far!
