An opaque class that holds a reference to an underlying TensorBuffer. Unlike Tensor, it does not have any shape or type information, so it is cheaper to construct/move, but the only thing you can really do with it is Unref it, which releases one of the references to the underlying TensorBuffer. IMPORTANT: If you do not call Unref(), you will likely leak tensor memory.
