[kxml_compiler]Pointer based accessor code generation

[martonmiklos]

Hi @cornelius, @dfaure

Recently I needed to create a tool (with Qt) which parses an XML, modify a few thing and write it back to file.
If I use the current kxml_compiler generated code I need to copy the whole parsed structure to do these modifications.

I was thinking about extending the kxml_compiler to add an option which would allow to generate classes having pointer based accessors.

What do you think about this approach?

That's interesting. But pointers always open up the question about creation and ownership...
Maybe unique_ptr would help (shared_ptr sounds like overkill).
