function block = line2block(line,blockwidth)
%LINE2BLOCK   reshape 1D character to 2D chaacter with fixed width
%
% textblock = LINE2BLOCK(textline,blockwidth)
% 
% reshapes to a 1D character or numeric array 
% to a block where the second dimension
% is equal to blockwidth. The length of the 
% array does not have to be an integer multiple 
% of blockwidth because the 1D array is padded with
% spaces or zeros to be reshapable.
% The last row or column will thus contains
% zeros or spaces.
