A ruby class to calculate English Gematria. This example uses a mispar hechrachi style correspondence table, but that can easily be swapped out for another table. Class supports raw conversion to number, mapping (breakdown of numbers), and reduction to a single digit (mispar katan mispari). ***Scroll down to see it in action.

I just started using cucumber. So far, I've tried to write my steps so that they are very reusable. These were written for mongoid, but they should work with ActiveRecord as well.
