New interface: AbstractZonotope <: AbstractCentrallySymmetricPolytope
Subtypes: Zonotope, LineSegment, AbstractHyperrectangle
Necessary methods: center (already there), generators (missing but trivial)
Benefit: We can generalize many algorithms currently only written for Zonotopes and we do not need to convert hyperrectangles to zonotopes anymore*.

The existing interface AbstractCentrallySymmetricPolytope is more general. In particular, the Ball1 is a centrally symmetric polytope but not a zonotope.

*However, it may still be more efficient if we access the generators more than once.
