+# CalcSkin: Add a Calculator UI!
+
+Add a calculator "skin" UI to your calc project.
+
+_ScientificCalculator_ can move to Release 2.0!!
+
+Using the classes you had for the scientific calculator, 
+add this JavaFX UI to the front of it.
+
+Run this project to see what you're going to be working with.
+
+The best way to integrate this skin class might just be adding the __CalcSkin__ 
+class to your project, and moving Console 
+out of the way and wiring it up.
+CalcEngine is a "fails all tests" class, and you should use the one from your project anyway.
+See the MainApplication class to see how to call it from your __main__ method.
+
+Making a simple 4-function calculator should be trivial for you at this stage.
+
+*BUT*, how about adding a column of buttons for x-squared, square-root, inverse (1/x), and
+exponent (x^y).
+
+Then you might add a column of buttons that do the Memory functions.
+(What should you add to the UI to make this easier??)
+
+Finally, work on adding the trig and log functions from the original lab.
+
+Feel free to work in your original groups, get everyone up to speed on this!
