comparison layer/TimeValueLayer.cpp @ 23:ca57f70b0e48

* Add Zero Crossings output from zc plugin (as well as Zero Crossings Count)
* Use brief friendly names for layers instead of full transform descriptions
* Clearer command names for editing commands
* Some efficiencies in drawing dense points in TimeInstantLayer
