Set processing function as virtual, to allow generic calls from AbstractDisplacementKernel
Change signal/slot connections when new samples are generated: the update signal is transmitted by the DisplacementFactory
Change code to fit DisplacementKernel changes.
Memory management bugfix: The displacement arrays are resized when samples are updated
BugFix: Ass missing line direction for middlepoints Samples
Change signal names
Use generic call for kernel computation
implement new signal/slots
Change signal names
