/** \brief This class is used to handle all Undo and Redo actions.
*
* This class bases on idea that any class can be represented
* as Xml structure which can be hold inside simple string.
* Each undo position entry holds whole structure of resource, what
* in case of standard resources should not exceed 50 kB. In case
* of memory consumption problems this can be changed to hold differences
* between two xml nodes only.
