[Haskell-beginners] Data.Vector in Haskell

[Christopher Allen]

To that end, I've got an example for firing up a little Cabal project and
using a sandbox for the dependencies here:
http://howistart.org/posts/haskell/1

The short version:

mkdir project && cd project && cabal sandbox init && cabal install vector
&& cabal repl

Hope this helps,
Chris
