1%'struct2xml': transform a matlab structure to a xml tree.
2%--------------------------------------------------------------
3% each field with char string or num vector is transformed into a corresponding  xml element
4% each field with a matrix containing n lines is transformed into a xml element repeated n times
5% WARNING: PROBLEM WITH HIERARCHICAL structures

8% t: xmltree reproducing the structure of Object
9% type 'save(t)' to visualize the xml text and save(filename,t) to save it in a file

12%  Object: matlab structure, possibly hierarchical
13%  t: optional input xml tree in which a new branch needs to be appended
14%  root_uid: optional uid of the xml element under which the new subtree must be appended
