                         goal is creating a library of functions which provides a layer of 
                         abstraction capable of hiding the geometric and topological 
                         problems which occur when one creates and manipulates spatial 
                         subdivisions. The study of arbitrary spatial subdivisions extends 
                         and unifies the techniques used in nonmanifold solid modeling.",
