+%% @deftypefn {Function File} @var{str} =  planeSurfGeo (@var{id}, @var{nloop},@var{loops})
+%% Generates a string for Gmsh Plane Surface format.
+%%
+%% @var{id} is the plane surface's identification number.
+%% @var{nloop} is the number of loops defining the surface.
+%% @var{loops} contain the identification numbers of all the line loops defining 
+%% the surface. The first line loop defines the exterior boundary of the surface;
+%% all other line loops define holes in the surface. A line loop defining a hole
+%% should not have any lines in common with the exterior line loop (in which case
+%% it is not a hole, and the two surfaces should be defined separately). 
+%% Likewise, a line loop defining a hole should not have any lines in common with 
+%% another line loop defining a hole in the same surface (in which case the two 
+%% line loops should be combined).
