Class: RectangleROIThresholdTool

This tool is exactly the RectangleROITool but only draws a rectangle on the image, and by using utility functions such as thresholdByRange and thresholdByROIStat it can be used to create a segmentation. This tool, however, does not calculate the statistics as RectangleROITool does.
