Add XY plots according to stations and function to prevent crash due to GEMGeometry.

Hello,

1. I added Global XY plots of stations 1,2,3.
 - Cesare found missing plots. 

2. Try and catch to handle exception for GEMGeometry.( Review results )
 - I added try and catch statements to plugin files for GEMGeometry. 
    If GEMGeometry is missing, it will help to skip these validation modules.
