Parent Handlers can be stacked to run in succession. Output is transfered as input into the child handler which can continue with it. If the parent Handler fails, all Child handlers also fail.
Handlers should now be added as objects, adding some flexibility to the developer.
Developers are still cautioned to take great care that Handlers work approriately. Handlers can potentially crash the SuperVisor if not taken good care of.
Event gets fired when an Event is modified by sending it to TaskStorage::modifyEvent. This allows components to observe changes and report these to the user. Might also be useful to cancel unwanted changes.
