If the class is just used internally to keep track of intersections of 
hyperplanes then it doesn't really matter what it is called since it will 
not be in the global namespace. In fact, you probably only need 
HyperplaneArrangement constructor and the hyperplane_arrangements factory 
in the global namespace.
