functions defined in there (gcc4.4) 
 

I have never seen the compilation work and the error to load the library is usually irrecoverable[1]
It is just confusing for users when the compilation then also fails

[1] Like missing local libraries

Use same algorithm as used in Marlin EventSeeder

use a vector instead of a map to make the order of particles deterministic and not depend on the memory layout
This is a problem if more than one primary particle exists.
Now runs with the same randomseed will produce the same result

 Updated TiledLayerGridXY segmentation, and added two functions to set and access the layer identifier string, which may be defined in the compact xml file.

Caution please. Do not update nor use this relase until green light comes. For details please see doc/release.notes.

 Updated WaferGridXY, allow to set and access different Magic wafer group. SiWEcal Barrel has different Magic Wafer size in each layer group, and SiWEcal Endcaps has different Magic Wafer size in each tower group.

   as these break ilcinstall
   ( if one wants to relocate DD4hep one only needs
     to change the one occurance of the path in
     the DD4hepConfig.cmake script)
