Detailed Description

A Cylinder.

Warning

Surfaces are reference counted, so only ReferenceCountingPointer should be used to point to them. For this reason, they should be using the static build() methods. (The normal constructor will become private in the future).

Returns the side of the surface on which the point is. Not defined for 1-sided surfaces (Moebius leaf etc.) For normal 2-sided surfaces the meaning of side is surface type dependent.
