% Recursively display the content of a structure and its sub-structures
%
% Input:
% - Xname/X     one can give as argument either the structure to display or
%               or a string (the name in the current workspace of the
%               structure to display)
%
% A few parameters can be adjusted inside the m file to determine when
% arrays and cell should be displayed completely or not
