A simple Menu Library
A Menu is light and easy to use. It's composed of a:
- an output interface to show which program is selected,
- a way to change the selection,
- a way to validate the selection and launch the linked program.
If you want a example on how to use it, look at the MenuExample program (http://mbed.org/users/rominos2/code/MenuExample/)
