A CRTP base class for coordinate objects.
CoordinateBase has partial specializations for 2 and 3 dimensions so its subclasses don't have to.

A public constructor with the same signature is expected for subclasses.

Return a fixed-size Eigen representation of the coordinate object.
The fact that this returns by const reference rather than by value should not be considered part of the API; this is merely an optimization enabled by the implementation.
