*************************************************
(1) Typo in smrblk.F.  NXMPCV is changed to NSMPCV
(2) smrvhl.F and smrvtx.F are modified to process event without 
    smeared VTX track parameter properly.
(3) Add simjpc/src/smrcmo.F and modified smrcvt.F so as to take into 
    account the effect of the multiple scattering when extrapolating
    CDC Track.
(4) Compile problem of simjlc/src/smrcvt.F by egcs1.1.2 is fixed.
(5) add simjlc/param/detect7.com as updated JLC detector parameter set.
(6) simjlc/src/smrcmo.F is further modified to fix a bug when extrapolating
    low momentum track.
(7) util/fortlib/src/up2hlx.F is modified.  If Pt of the particle is 
    less than 1 eV, Pt=1eV is used to get helix parameter to avoid 0 
    division.  This is required to save all LUJETS common in 
    Generator:Particle_List bank.
(8) Avoid pivot move when construct the smeared VTX helix parameter 
    in the subroutine smrvhl.
