	* Now its possible to only add outports (not only inports)
Merge pull request #5 from knime-ip/twovaluestocellnodemodel

Port handling of TwoValuesToCellNodeModel improved
Fixed JavaDoc in several classes
Fixed bug 4751: Label Transformer works again

	* slower than before, but correct now
	* speed-up caused inconsistencies and was simply wrong
Added sources of JEP to classpath
Fixed IterationOrder Bug 4403 in ImageCalculator

	As soon as ImgLib2 supports cursors created from
	RandomAccessibleIntervals with arbitrary iteration order we can
	get rid of the unnesscary wrapping at the moment the only really
	"slow-down" takes place, if the input only consists of unwrapped
	CellImgs. For any other Img combination it would be wrapped anyway
	OR the wrapping doesn't influence the performance
Improved Comparator Nodes for Testing

	* Added fall back if iteration orders of incoming images do not
	* match (which is valid, if you just want to make sure, that the
	* content of the image didn't change

	* Added several more checks on ImgPlus (e.g. metadata, dims,
	* type,..) SOme of them need be activated later.
Fixed NPE in Loops for IMGJepNodeModel

	* factory couldnt be serialized
	* using default factory now
maxentropy- and yen-thresholding methods are not working either and currently not supported!
warning if not all selected dimensions are present in the IterableIntervalsNodeModeL
Workaround to not exclude the complete thesholding methods that do not work on few image types
bugfix 4750: bounding box wasn't placed correctly
bugfix 4747: moving image on repaint event
bugfix 4749: npe in interactive segmentation view
another side-effect of bugfix 4747 removed
