Coffee Ratio Thing

This app made to help home brewers brew their coffee by calculating a the grams of water needed,
and run a timer all in the same screen.

With the addition of the segmented control:
When you are in Grams mode, the number you enter into the big box is coffee in grams and the large output is the water in grams.

When you are in TBSP mode, the number you enter into the big box is coffee in tablespoons and the large output is water in cups.
