HARMONY proposal #3: 'quick' L1v5 with generic Tasks and Changes.

[Lucian Smith]

One final suggestion, this from Frank.  It would require an L1v5 release of SED-ML, but is fairly straightforward, and might not be too difficult to accomplish.

To summarize:  L1v4 introduced an entirely-KiSAO-defined 'Analysis' subclass of Simulation.  Frank would like a similar entirely-KiSAO-defined 'Task' and 'Change'.  Nobody at HARMONY had any objections to this, and it seemed relatively straightforward to achieve.  Given that we had to introduce a 'WaterfallPlot' and a 'ParameterEstimationReport' to L1v4 for parameter estimations, I think we should probably introduce an entirely-KiSAO-defined 'Output' too.  (And at that point, maybe we should do the same for Model?)

Opinions?  I think if this is the only change we wanted to make, I could crank out a new proposal in a week or so, assuming I had the time to work on it.
