[0.1.7 REWRITE] Codebase overhaul.

~ Codebase split into two sub-packages
~ net.transit.network for transfering between objects
~ net.transit.type for type registering and conversion

+ Added new interfaces (INode and ISystem)
+ More documentation
+ (Kinda) Working build

- Removed unnessairy interfaces (IGenerator and IConsumer)
- Removed base types

~ Restructured type system
