Perpetual Paschalion calculator

This script will calculate Pascha and associated feasts (Palm Sunday, Ascension, etc) for any period of years. You can enter any sequence years, at most 99 years apart.
Alternatively, it can also calculate a perpetual table of numbers used to calculate a Paschalion, such as one would find in the back of a Typicon. Thanks to Gregory Douglas for information leading to the creation of this feature.
