Iteration event type

An event type what will iterate every time its repeated based on the assigned people to the event.

So if the setup would be something like this..

Title: Run updates
Who: Peter, John, Tim
Repeat: Weekly, once
From/To: Monday/Friday

Than it would look something like this:

week #1: mo - fri, Peter: Run updates
week #2: mo - fri, John: Run updates
week #3: mo - fri, Tim: Run updates
week #4: mo - fri, Peter: Run updates
...

But it should adjust itself automatically so, if you decide to add a person (Tom) to the bottom spot, after week 4 than it will look like this:

week #4: mo - fri, Peter: Run updates
week #5: mo - fri, John: Run updates
week #6: mo - fri, Tim: Run updates
week #7: mo - fri, Tom: Run updates
week #8: mo - fri, Peter: Run updates
