A really cut down version of the vector class.

Note: this does not match the true std::vector class
but instead is an approximate, so that SWIG knows how to wrapper it.
(Eg, all access is by value, not ref, as SWIG turns refs to pointers)

And no support for iterators & insert/erase

It would be useful to have a vector<->Lua table conversion routine
