%'cell2tab': transform a Matlab cell in a character array suitable for display in a table
%------------------------------------------------------------------------
% function Tabchar=cell2tab(Tabcell,separator) 
%
% OUTPUT:
% Tabchar: column cell of char strings suitable for display (equal length)
%
% INPUT:
% Tabcell: (ni,nj) cell matrix of char strings to be displayed as  ni lines , nj column
% separator: char string used for separating displayed columns
