PlugIn modification for Elisa@Ellenberg Lab

Modify Gwen's ImageJ plugin, to enable controlling the thickness of ROI (band) and the distance of the ROI from the thresholded region for measuring intensity at the edge of segmented structure:

Current modification is a quick and dirty version:

instead of

- threshold-> detecting edge -> define ROI +/- 1 pixel width from the edge
(option:= "outline")

do as follows:
- threshold -> dialate the thresholded region by "max""min" option -> define ROI +/- 1 pixel width from the edge
(option:="nothing")

further addition: control the ROI strip width (variable input)
