Detailed Description

This helper class contains all of the changing cluster data, and is used to ensure that updates occur atomically and quickly.

Do not create directly!

In general, you will want to access cluster data via the ci global variable. However, if you want to take a top-down snapshot of the entire cluster state, then you may do something like:

snapShotState = ci.d

And then use "snapShotState" in a similar manner to ci:

print [x.name for x in snapShotState.entities.values()]
