+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
