While I understand the reasoning for it, I dislike the name vector for
arrays. A vector to me, is a geometric object with a length and magnitude,
not a random collection of whatevers.
Jonathan M Davis:
The biggest difference is that a vector has capacity separate from its
size/length. You can efficiency insert elements at the end with a vector -
amortized constant time usually - but you can't do that with a built-in
array because it would have to reallocate every time.
