CalorieEditor added as functionality update.

The calorie editor was implemented as well as having implemented a
simple version of the functionality with the exception of the "Since
Meal" edit text.  Whatever caloric difference has been consumed by
midnight rolls over into the calorie bank at the bottom be it positive
or negative.  The estimated lbs field will be the current weight minus
the bank divided by 3500 for calories per point.  This will reflect
estimated gains or losts.  Weigh In button is also not implemented just
yet.
