The SOP asset for collecting keyframes (from input node, another node by path, or channels of Animation Editor), caching keyframes to disk files, and copy keyframes to other nodes. 

This node works with REAL keyframes, so users can still easily tweak the REAL keyframes!

It is NOT based on CHOP, so it DOES NOT sample the animation for every frame!

The keyframes are converted to Detail level attributes for easier modifications.

When caching the keyframes, just cache to ONE bgeo file. NO NEED to cache a sequence!
