Menu system

This is the prototype menu structure that will be accessed primarily using the rotating bezel (to scroll up and down menus) and the select/back buttons on the side of the watch.

Pressing select will open the main menu. As previously discussed, turning the bezel will scroll through menu options (with an audible and tactile 'click' feedback so the user knows how far they have scrolled). If the user pauses for more than half a second after scrolling and without pressing a button, the current menu item is spoken in the earpiece.
