/*
* This is the central method of the whole Dataflow engine as it executes the patches.
*
* A breath first search over the entire graph is done, starting from the rootSet.
* All patches that have no connected inlets are part of the rootSet.
*
* The algorith is the follow
*
* 1) push all elements from the root set into the execution queue
*
* 2) dequeue a patch from the execution queue
* 3) if execution criteria is met execute it *1
* 4) propagate the values of all changed outlets and add the receiving patches to the discovered set *2 *3
* 5) goto to step 2 if the execution queue is not empty
* 6) move all elements from the discovered set to the execution queue
* 7) goto step 2 if the execution queue is not empty
* 8) finish the frame
*
* *1 right now the only criteria is 'execute allways'
* *2 outlet values propagation and patch enqueuing are done from first to last outlet.
* *3 order of discovery is maintained during execution.
