[CASHeW-s-editor-patches] To XMLs and XMLizable added....

[Ravish Bhagdev]

Hi,

I am attaching a patch.  I have added an interface XMLizable to the Model 
subpackage and written toXML instead of toStrings in all the models.  At the 
moment, the model is being saved in XML properly, what remains to be done is 
parse it back and create the diagram objects back from that...(patch attached)
