Improvements to Documentation #28

The documentation is pretty brief, some things that could be expanded on...

1. What is the significant of namespace? Can all packets have the same namespace or the namespace should change and if so how?
2. When dealing with multiple packets, do you define each packet in its own file? How does this framework scale?
3. Does a packet with no data require a type of ByteNet.nothing?
4. A sample project to better understand how packets are defined and used in a project would be incredibly helpful
