Refactor how Computed values are calculated. (#44)
# Pull Request ## Issue #40 ## Description The previous implementation had computed calculations happening in several places, that was quite bad(tm). Making the calculation of 'Computed' values it's own step after values are calculated making things easier to test. ## License By submitting this pull request, I confirm that my contribution is made under the terms of the projects associated license.
