[Rivet] LHCB_2010_S8758301 Rivet analysis (no HepPDT dependence)

[Alex Grecu]

Dear all,

I attach to this message the improved version of the RIVET plugin code 
for the  prompt Ks0 production cross-section analysis.
The main change is that I added (statically) the table of lifetimes as 
used by the LHCb collaboration so there is no need anymore to  link 
against the HepPDT library. For the LHCb recipients this code will be 
easily to generate using a script from the package with the Gaudi 
component for RIVET.
This version of the analysis also uses the correct units as defined in 
RIVET so the scaling constants are no longer hard coded into the plugin 
but used from the Rivet library.
Last but not least, you'll find in the archive the plots for a 10M 
events run using Pythia 6:421 standalone with the Perugia0 tune as well 
as the corresponding .AIDA file.
All tests were done exclusively using HepMC 2.06 which will become very 
soon the official version used by the LHCb framework as well.
Please, let me know if you consider any other modification must be made 
before final release!

Best regards,
Alex Grecu

PS: The .plot and .info files are unchanged.
PPS: For the RIVET team. Please, do not forget to strip the final "B" 
from the plugin name before release. As I previously wrote, it is in 
there to distinguish the analysis from the unvalidated one present in 
RIVET 1.6.0.
