sip doesn't handle any pre-processor directives (#if, #define, etc)
unless they are within a %<some sip directive>/%End block. #include
in a %HeaderCode block is legal, as is #define, #if, etc. in a
%MemberCode or %C++Code block.

Good solution. You should also be able to do:

    typedef MpVector3D MpPoint3D;

which is really what you mean in the #define above. Semantically
it's the same thing, but I'm not sure if the class declaration
would generate a lot more code or not.
