v2.0.0

• Pupil transform algorithm based on Lundström & Unsbo (2007);
• The previous aperture scaling algorithm has been superseded by the pupil transform algorithm which is not only faster and more accurate for higher orders, but also includes translation and rotation for circular and elliptical pupils;
• Functions to convert from Noll and Fringe single-index ordering to the standard ANSI order;
• Log transforms of the Zernike polynomials are now plotted for high orders;
• Various improvements and optimizations.
