This avoids a lot of problems because java
- does not know unsigned values
- jvm and dalvic do not internally support byte and short
- sqlite does not know them either
- model package contains mostly shared interfaces (UI+service), not named GB*
- impl package contains implementations of those interfaces, named GB*
the impl classes should not be used by the service (not completely done)
- the service classes should mostly use classes inside the service and deviceevents
packages (tbd)
Every device now has two packages:
- devices/[device name] for UI related functionality
- service[device name] for lowlevel communication
