PointArray is a data structure that organizes the solutions found by a solver. Each HomotopyNode object V has an associated PointArray accessed via V.PartialSols. A "fingerprinting" scheme allows for equality of points to be checked quickly.
The object PointArray is a type, with ancestor classes MutableHashTable < HashTable < Thing.
