NOTE: Version 4 is still a work-in-progress!

• The latest version (version 4) is available on the master branch.
• The last version of version 3 is available at the v3.0 tag.
• The last version of version 2 is available at the v2.0 tag.
• The last version of version 1 is available at the v1.0 tag.

Version 4 breaks compatibility with version 3, in order to introduce the following features:

• Entities now have matrixes instead of explicit X, Y and Z properties. This is necessary to support hierarchical matrix combination.
• Worlds no longer have an Entities property. Instead the dependency injection hierarchy is used to track entities in the world. This means entities you inject in the constructor will automatically be added to the world. To add entities to the world, you now need to inject IHierarchy and INode and call _hierarchy.AddChild(_hierarchy.CreateNodeForObject(entity)). We'll have a cleaner API for entity management in the future that wraps this call.
• We expect to significantly rework the platforming and bounding box APIs to make them work cleaner with the new matrix composition system.
