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.
