change vertex(3) offset from 237.5 to 187.5
Modify calorimeter.f , beta_geom.inc and sane_mics.inc

Calorimeter.f :
1) Put ECAL in correct position -187.5+cal_drift+cal_depth/2.
2) Add variables in sane_misc.inc to have the volume id number
  for each object.
3) Remove subroutine divi_cal

beta_geom.inc :Increase the horz_blocks from 28 to 32
sane_misc.inc : add the integer for the volume ID
Remove test on random number to weight thron events by cross section
Change codes gukine.f, guout.f, gustep.f, lucitehodo.f, forwardtracker.f,
sane_acc.inp, sane_cwn.inc, ufiles,ugeom.f, uginit.f
