point3d operator+(const point3d&, const point3d&) 
"must take either zero or one argument" - your giving it two args, thats why
its fussing.  I've not done it in a while, so I don't remember how to force
it to accept two, if you can at all.  I think you need to make a function to
do it rather than an overloaded operator.
