tensor reference counter vs storage reference counter?

[pl-csci]

I'm very new to this, enjoying it immensely.
But bear with me. Apologies if I have no idea what I'm talking about:

In the .h you prototype these:

void tensor_incref(Tensor* t);
void tensor_decref(Tensor* t);

but these are yet not defined in the .c file.
I don't see how these would be useful given the other functions you've built. Maybe there's a case for them. Did you mean to prototype the storage increment/decrement functions? (although they aren't used directly either, don't need prototyping).
