this is for linux only, and more for people to break it down and check it out. This has both a playblasting script and a simple fast caching (fast b/c it hides the fluids while it caches)

Linux only b/c it will make a directory using the system function and its in the linux format, I didn't care to make it cross platform, altho I may later.

I didn't originally make this full featued since I normally would copy and paste this into my script editor and make changes based on what I need to cache. If I added all the cache options it would be too many. So it defaults to only caching density and temp.
