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
