Conditioning Average (#495)

* first commit

* fixed a bunch of things missing in initial commit.

* parameters renamed for clarity

* renamed node, attempted update cond list

* to_strength removed, it is now normalized

* removed comments and prints. Attempted to apply to every cond in list again but no luck

* fixed repeating frames after batch using deepcopy

* Revert "fixed repeating frames after batch using deepcopy"

This reverts commit 1086d6a0e1f5c5c9247312872402ff8e60358fe1.

* Rewrite addWeighted to use torch.mul iteratively.
