Created animations for sunny and cloudy days in the midDayView
Created an animation for rain.  It needs improvement, but is a start.
Refactored a part of the main model function into a helper.
Changed how the model modifies popularity so that it decreases if you do poorly. It doesn’t quite work as desired because differences between the customer and model classes’ assumptions need to be addressed.
Added money to Inventory, but to lemons only.
started work!
functionality done.

Money works on all ingredients. Aesthetics are terrible.
Update inventory and recipe views, added images to postDay view and removed inventory summary.
Added customers to postDay depending on popularity, fixed preDay bag image to be opaque instead of transparent, cleaned up code in views.
Modified willBuyAtPrice method to use a linear model.
Modified how popularity is calculated, modified thresholds for customers liking lemonade, and added a very small amount of randomness to whether or not a customer likes lemonade.
