priciple program to optimize a car trajectory in a curve using
Metropolis algorithm

Written by F.Calvayrac, MXinhao and 

Should compile on any platform (works fine on a
standard linux distro using Intel free f90 compiler)
just edit the Makefile and type "make"

parameters to be changed in params.f90

outputs several files which can be plotted
with gnuplot using the "plot" script which 
can be called by a "./plot" command or "make plot".

outputs as well postscript files of the optimized
trajectories.

To be done : the program is not interactive enough,
and it should run for other tracks than 90 degrees
turns joining two straight lines. Easy to do.
