***Note from Migration:***
Original Title was: RasterExpressionEvaluator should support duplicating rows and other copy/paste functionality
The various tester and attribute creators allow one to copy/past or duplicate a row in it's entirety. It would be nice if the RasterExpressionEvaluator had the same right-click context menu as the other transformers.
Currently right click does nothing, you have to go into the cell and select the contents to copy, and then go into the subsequent cell and paste and then set the interpretation manually.
