Subject: Begin NDMF integration

It mostly works. Weight parameter is being set to 0 which is causing it
to not work. Easy enough to fix!

TODO:

* animations should stay in memory, never save to disk unless debugging
* YOTS_weight param should be set to 1
* Generally clean up, so much "if null keep going" bullshit
