Version 0.5

This version consolidates the app into a single page operation. It
returns the beer number as a number usually larger than one in a modal
popup and suppresses divide by 0 errors returned by submitting a blank
form or a missing value.
First AJAX Beta

Version 0.9.0 builds on the previous in attempt to make the app more
efficient by calculating and returning the value through AJAX instead
of purely PHP. This is the latest stage of the app and is very much
still a work in progress.
