New MC & Reconstruction software version (5.13)

Dear collaborators,
A new version of the FINUDA code has been released (fidamc513 and 
fidarc513) and is available on the FINUDA web site (temporarily also from 
http://nppbs3.ing.unibs.it/finuda). The new version contains a lot of 
improvements, mainly:

- new geometry of the vertex region obtained from mechanical survey
  This new geometry improves considerably the quality of the vertex 
  reconstruction

- Activation of the two helix algorithm for the K+K- reconstruction after 
  correction of the last bugs. The new algorithm works well and improves 
  the accuracy of the kaon momentum evaluation

- Treatment of ambiguities in hit assignment to tracks and improvements in
  Tofone slab connection. Efficiency in track recognition has increased.

- P.R. and reconstruction of neutrons. Now, candidate neutrons are 
  recognized and displayed in the event display

- Moreover: Tofino CDF shifts evaluation, increase of the information 
  contained in the standard n-tuple, improvements in cosmic ray  
  reconstruction, and other minor changes that are described in detail in 
  the version documentation.

Regretfully, it was not possible, in this version, to consider to 
inclusion of the new track P.R. proposed by the Japanese colleagues, due 
to the considerable impact of this completely new procedure on the present 
program structure and the urgent need to have a new version of the 
program to make available so many improvements and allow for a new data 
production.

I plan to take it into account for the forthcoming new version of the code
which I suggest should include :

- New track P.R. strategy from external to internal hits (to be checked
  for backward compatibility)

- K-nucleus background generation in the MC  (some final test needed)

- mini-DST production in Zebra format and READDST procedure producing
  paw n-tuples (ready)

- root DST production including noise information and possibly:

- detector alignment as result of alignment procedure performed

- information on detector efficiencies in the MC and track fitting

- correction of chamber and straw times for CDF shifts

- ...........................
