loads parameters from geometry file, saves each data line from this file in geo, creates and  returns the  list_of_geos with already set relations between children and parents.

Status

Modules GeometryObject and GeometryAccess are implemented in C++ (ImgAlgos) and Python (pyimgalgos)

Todo list just before vacation

• In addition to X, Y, Z pixel coordanate arrays add pixel "area" array
• Make better interface for basic elements (2x1) pixel geometry
• Use new geometry in image producers
• Add geometry file producers for xpp-CSPAD and ePix

• Automated GUI-based system for alignment of geometry objects
