A type for *points* (as distinct from vectors).

- newtype Point v = P v
- origin :: AdditiveGroup v => Point v
- (*.) :: VectorSpace v => Scalar v -> Point v -> Point v

# Points

`Point`

is a newtype wrapper around vectors that we wish to treat
as points, so we don't get them mixed up. The distinction is
important: translations affect points, but leave vectors
unchanged. Points are instances of the `AffineSpace`

class from
Data.AffineSpace.
