%  function str = fill_dim(cdfid, ndims)
%
% DESCRIPTION:
%  This function fills the ith row of an array named 'str', with the
%  the name of the ith dimension in the netcdf file with id number
%  cdfid.  ndims is the number of dimensions.  Each dimension name is
%  initially allowed up to max_le letters but the number of columns in
%  'str' will be expanded if necessary.
% 
% INPUT:
%  cdfid: the id number of the netCDF file under consideration.
%  ndims: the number of dimensions of the netCDF file under consideration.
%
% OUTPUT:
%  str: the array that receives each dimension name as one of its rows.

% CALLER:   general purpose
