Changing the internal representation of Point / Pointf / Point3 / Pointf3 to Eigen Matrix types:

Browse source 
Changed the Point3 / Pointf3 to composite Eigen Vec3crd / Vec3d.
Point3 is no more derived from Point,
Pointf3 is no more derived from Pointf.
Introduced Transform2f/3f/2d/3d types as aliases to Eigen::Transform.
