Exporting in Milkshape - Improvements?

What could we do to improve exporting from Milkshape3d?

I say figuring out a way to get the InTan and OutTan quaternions for bezier and hermite interpolation (I got really close to solving this, but c++ is not the easiest programming language to understand and kdub's exporter doesn't help either).

That is the only thing I would like in a Milkshape3d exporter because all the rest is easy to put into a .mdl file.

I sort of guessed how the interpolation should go until it started looking about right. Feel free to test and give feedback on its accuracy.

I'm pretty sure that rotation is just linear, so I didn't mess with that at all.

Add attachment points, geoset anims, and cameras and I'll be very grateful. Thanks to you my first model is almost finished.
