        EXPWRITE - write an Argus file from a structure given in input

           This routine write an Argus file form a structure containing the fields:
           x and y of the coordinates of the points.
           The first argument is the structure containing the points coordinates 
           and the second one the file to be write.

           Usage:
              expwrite(contours,filename)

           Example:
              expwrite(coordstruct,'domainoutline.exp')
