Continuesly executing nodes that push out results

[gab1one]

Note This probably requires changes in SciJava core.

A command should be able to push out results (which are properly post-processed) continuously without getting re-executed. Example use case:

• A command that reads images from a webcam and pushes them into a processing pipeline.
  • Inputs are static (eg. selected Webcam, processing parameters)
  • Output is updated 30 times a second with the current image from the webcam.

another (more simple example): you have one input and n-outputs of the very same type. however, you want to push the n-outputs directly after they have been computed rather than collection them and output them as a list / array or so.

OutputRowSyncService

• Create OutputRowSyncService:
  • Commands can call push(this) method on it to signal that they want to offload their results to the service.
  • A node can register as a Listener to this service via a registerListener(RowSyncListener) method, it will get called whenever a result is added to the service.
  • this service harvests the results from the command, (if needed post-processes them)
