Java doesn't have unsigned shorts, bitmasks occur instead #14

I think there might be an issue with some of the fields being read out / unmarshaled using .readShort(), as this results in high end shorts (>32k) being negative. This could cause a few issues with lookups of enumerations - if they were populated that high.

So far in various simulation tools, I've encountered issues with ElectronicEmitterPdu, EntityStatePdu and the classes used within (EntityID, etc) but I'm sure any part of the standard that references 2-bytes needs to be unsigned, so probably stored internally as an int that's masked (0xFFFF). Some are, but some aren't. Unsure on the lack of uniformity.

Raising this for further discussion on resolution or my use-case. :-)
