Description
make a new input GUI, that is all imageJ2, replacing IJ1 gerneric dialog stuff with however imageJ2 should do, it... swing. Some general inspiration from JACoP would be good.
The Inpu tGUI should deal with settnig all the input parameters, and not bother with eg. images display,
But could display image parameters that are under 1 sec to calculate, eg mean, max, min, and perform the input data sanity checks and show red flags for stuff that is missing or easy/fast to detect as bad.
