copy an object

[Yuval]

I have an object of a class I wrote myself, and now I want to copy it.
How do I do it? The reason I want to copy it is because if I simply
use copied_object=existing_object, when I later change
"copied_object", "existing_object" is changed as well, and I dont want
it to happen.

Thanks.
