Should be able to deal with duplicated origin points: True should equal False

in another test it says:

The definition of Point3d should be provided somewhere for the user somewhere. Currently what is going on in preloaded is completely opaque.

Even better don't make the fucking class at all since it's just an instance of (Int, Int, Int).

Relies on runner concatenating preloaded and solution for the type annotations. Explicitly import type annotations in the solution setup if you wish to use them, as the user trying to import anything from preloaded will make it fail to run.
