stepping in the Component/ViewModel architecture

What would you like to achieve?
Lively Morphic had a very nice overlay on the native JavaScript timing functions -- stepping. In order to run a script on a Morph every n milliseconds, the call was simple: morph.startStepping(<scriptName>, <time in milliseconds) (the order may be wrong, I'm doing this from memory.). morph.stopStepping() stopped the stepping (of all stepping scripts).
It could have been improved (basically, UI/methods to view and control individual stepping scripts) but it was a huge improvement over the native JS calls.
The problem is that it was tied to Morph, and, in a Component/ViewModel architecture it's not clear if this is available or how to use it. So guidance is appreciated.

How are you trying to achieve that
I assume the simplest way to do this is just to attach the stepping methods to ViewModel

Version: Please paste the lively.next commit on which the problem occurred here (use the copy button of the Version Checker in the bottom left corner).

Start by locating the existing Morph stepping entry points, morph.startStepping and morph.stopStepping, and compare them with the Component/ViewModel architecture. Determine whether stepping should be exposed through ViewModel or another API, then document the chosen behavior and how individual stepping scripts are controlled.
