ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

	Readme: In the following pseudo code, [] indicates a subroutine.
	Sometimes I choose to write the subroutine inline under the [] in order to maintain context.
	One important fact about the way rollbacks are handled here is that we are storing state for every frame.
	In any real implementation you only need to store one game state at a time. Storing a game
	state for every frame allows us to only rollback to the first frame where the predicted inputs don't match the true ones.


	==Constants==
	MAX_ROLLBACK_FRAMES := Any Positive Integer # Specifies the maximum number of frames that can be resimulated
	FRAME_ADVANTAGE_LIMIT := Any Positive Integer # Specifies the number of frames the local client can progress ahead of the remote client before time synchronizing.
