Fix/explanation methods

[liz-is]

Resolves #73 - however sadly this only fixes two Pyright complaints that were associated with using _Explanation__global.

Pyright still complains when _spatial is used, and I don't understand the relevance of the error it reports:

 "None" is not iterable
  "__iter__" method not defined

(I would hold off on merging this until after #48 is merged, it's not urgent)
