Improvements to the CMC command

[Aenimus]

Newly visited locations are appended to the right; rectified the pill prediction logic accordingly.

Accounted for unknown locations.
Added line breaks to predictions.
Added more tests.
Removed unused constant.

@jaadams5 I thought new state was appended to the left, not the right. I've changed the logic accordingly (it actually made it simpler). Sorry.

I think it would be good to put this functionality behind a param. Like cmc needed or something

@jaadams5 please don't merge the branch while people are working on it

[gausie]

Looks fantastic! All we need now is a little bit of inline documentation on what the nature of some of the more complex functions are actually doing - this is quite complex and it would be good for someone coming back for maintenance in the future.

@jaadams5 This is now complete and ready for review/merge. :)
