Using the calculator

HANDWRITING RECOGNITION
-----------------------
The symbols.unipen file contains the models it matches your handwriting against. If you delete this file you start from a blank canvas. The Train window that appears behind the main one if you run the jar file, can then be used to train the calculator specifically to your handwriting. Write an example of each symbol (R=sqrt and P=pi), click learn and then click save when you are happy. Enter around 5 examples of everything for reasonable recognition.
