feynman_kac_1d():
  Fortran77 version.
 
  Program parameters:
 
  The calculation takes place inside an interval.
  The solution will be estimated at NG points
  on a regular spaced grid within the interval.
  Each solution will be estimated by computing    10000 trajectories
  from the point to the boundary.
 
    (X/A)^2 = 1
 
  The interval parameter A is:
 
    A =    2.00000    
 
  Path stepsize H =   0.100000E-03
 
  X coordinate discretized by   23 points
