Finish implementing dyadic tensor evaluation about grassmann.jl HOT 3 CLOSED

Another issue (with a positive metric signature):

The tensor evaluation feature is not currently fully implemented, since it's not completely essential to do math with geometric algebra.

It is planned to eventually fully implement this, but it's not a high priority at the moment and requires a lot of detail work to get right for every type of basis (there are a lot of different nuances).

I can't give an exact timeline at the moment for when I'll finish implementing it, since I have a lot of other ideas I want to work on as well. There's a lot of stuff that can still be improved and added.

I think the error you got is due to the fact that I previously used a Bool there, but then I generalized it so it can take on values other than 1 and -1, which is why it expects currently a Bool. In other words, this feature has not been updated to the new format where no longer only use a Bool.
