Bodymap

In order to make bodymaps more user friendly especially on mobile devices

- Make bodymap read only upon user logs out or clicks done. 
- Make signature box read only after pressing done.

This is not user friendly on a mobile phone for larger body maps. When in portrait mode, you cannot move to the right of the map. When in landscape mode a user has to be very precise if they want to navigate up or down the screen. Any touch in the area on the bodymap results in a mark being recorded on the bodymap.
