ObjectExtraction: Replaced OpLabelImage with the one from lazyflow.
ObjectExtraction: Refactored OpRegionFeatures to use OpArrayCache and use Output stype=ArrayLike
OpObjectExtraction: Use a compressed cache for object centers for much better performance.
PixelClassification: Comment.
BatchIo: Comment.
workflows: ObjectClassification: Minor cleanups.
ObjectClassification: Renamed OpToImage to OpRelabelSegmentation
ObjectClassification: Fixed two trivial crashes.
Implemented BlockwiseObjectClassification applet and workflow, which requires "normal" object classification applet to provide the classifier.
logging: Added blockwise object classification logger to config.
objectClassification: Commented out serialization code that isn't working right now, and added FIXME warnings.
DataSelection: Added a quick hack to allow multiple data selection applets to be used in batch mode.
BlockwiseObjectClassification: Added a custom batch results viewing applet.
debug code.
BlockwiseObjectClassification:  Support changing the blockshape and halo via the applet drawer, and save them to the project file.
