Progress report 7 July

Added constructor with native handle parameter at the code generator for classes that hold handles to native pointers and also classes that hold native pointers. Made a Convertor class that applied on parameters converts them from managed to native and back. Analyzed other packages to see if the current code applies on other situations like getting an Iterator and iterating through a list of shapes and the code seems to apply well on these situations.

I'm making the final adjustments to the code generator, operation that should take half a day and after that I will start wrapping.
