Current draft of the massive changes for FP8 with "tensors" being passed around instead of pointers. Only putting this up now so others can give feedback on the overall design & style (not ready to be integrated yet).
It's simpler and more elegant than my previous version of FP8 by far in my opinion, and it solves a few other problems making things cleaner elsewhere. But it does change a lot of code...!
