CreateVector(STACK)

Stack

Stack(In)	Top	n
Stack(Out)	Top	a vector

creates an empty vector (pre-allocated for n elements)

The empty vector can then be filled with insert elements without having to reallocate it internally.

Note: The reallocation of a vector on modern machines is basically a very fast operation and can only be measured in the range of many millions of elements. Preallocation is therefore an unnecessary micro-optimisation for smaller vectors.
