1%'struct2xml': transforms a matlab structure to a xml tree.
2%--------------------------------------------------------------
3%
4% each field with char string or num vector is transformed into a corresponding  xml element
5% each field with a matrix containing n lines is transformed into a xml element repeated n times
6% each substructure of the input matlab structure is translateed into a subtree in the xml object
7% it is also possible to append a subtree to an existing xml object t
8%
9% t=struct2xml(Object,t,root_uid)
10%%%%%%%%%%%%%%%%%%%%%%%
11% OUTPUT:
12% t: xmltree reproducing the structure of Object
13% type 'save(t)' to visualize the xml text and save(t,filename) to save it in a file
14% to set the title tag of the file, type t=set(t,1,'name','titletag')
15%
16% INPUT:
17%  Object: matlab structure, possibly hierarchical
18%  t: optional input xml tree in which a subtree needs to be appended
19%  root_uid: optional uid of the xml element under which the new subtree must be appended
