Subject: [PATCH] Noticed that I had forgot to include NiObject.cpp in my last
commit... unfortunately I've already started splitting off classes into their
own files so that's included in this commit as well. I also noticed that I
never implemented the member functions of Ref! I still haven't, but I was
just surprised it's been compiling without complaint.
