classifiers: Renamed classifier ABCs and defined a new ABC for "pixelwise" classifiers.
Slot, Operator: Refinement to cleanUp behavior: Don't automatically call resize(0) on disconnect during cleanUp.
(Otherwise, this causes problems for remaining OperatorWrapper connections.)
classifiers:
- Added example pixel-wise classifier
- classifier training and prediction operators can handle either type of classifier and classifier factory.
Removed obsolete test.
OpStackWriter: Fixed an assertion message.
OpSelectSubslot: Don't require all inputs to be ready.
