There is now a Collection type class, which allows us to augment collections collections with more functionality without changing type signatures of other functions too much. See haddock for more Info.

The spawn system is such an augmentation. If you want to know how to use extend the collection type class, check out Objects/Spawner.hs

• Fix bug in geometry (collision detection)
• implement object collection data type
• implement interval tree for space querying
• reimplement spawner logic
