ReadySquid Caffeine

Caffeine is a small utility I wrote to calculate and graph the amount of caffeine in your blood over the course of a day. I wrote this program primarily to learn how to use the JFreeChart library. Caffeine is not meant to be an accurate calculation of the amount of caffeine in your blood, but merely a very loose estimation. I researched how long caffeine remains in the blood and several sources indicate caffeine has a "half-life" of four to six hours. This utility sets that estimation at six hours. On top of the inaccuracies introduced by that, there is also the inaccuracy of correct caffeine content in products.
