$ Total number of grids (NGR). The code assumes that the first NGR-1
$ grids are the input grids and the last grid is the target grid in
$ which the output fields are to be interpolated. It also assumes
$ that all the grids have the same output fields switched on

 'grd2'
 'grd3'
 'grd4'
$
$ In this example grd1, grd2 and grd3 are the input grids. For each
$ of these grids a mod_def.grdN and an out_grd.grdN are available.
$ The target grid is grd4, and a mod_def.grd4 is also made available.
$ Upon execution of the code an out_grd.grd4 is generated via
$ interpolation of output fields from the various out_grd.grdN
$ (N varying from 1 to 3) files.

$ Interpolation scheme
$   0: Linear (all grid types)
$   1: Linear with extrapolation of wetnodes (unstructured)
