PolyGeom encapsulates the functions to generate centroids, normals, etc given the geometric information. It is meant to be used simply as a static class. Its only data member (a static) is its tolerance.

andzvolume computes the volume under the curve (covered volume). Does so using Scardovelli and Zaleski's direct formulae. The normal has to be all positive numbers. The normals also must be ordered from lowest to highest.
