Debug/boxes

Improves the test reporting:
```
Vector3D.+: Parameters(Generic Vector 3D -> miniboxing.example.vector3D.GenericVector3D@67698268)                :   45.95474
Vector3D.+: Parameters(Specialized Vector 3D -> miniboxing.example.vector3D.SpecializedVector3D$mcD$sp@5c62592d) :   23.38811
Vector3D.+: Parameters(Miniboxed Vector 3D -> miniboxing.example.vector3D.MiniboxedVector3D_J@48412763)          :   10.42400
```
and also does some encoding nonsense to make the project compile on my machine.
