 * Equivalent of JavaFX's {@link Interpolator} (in fact the class extends it), in {@code Flutter} they

 * 
 * Aside from just a "rename", the protected method {@link Interpolator#curve(double)} has been made public
 * since some curves need to access other curves' algorithm; also adds a method to quickly create a {@link FlippedCurve}
 * from any implementation.
