BooleanIntersection for a single input set

In the latest WIP, I’ve added a test command, testAllowOneIntersectionSet (it will not autocomplete, so you have to type it out). If you call this and click on the option, the BooleanIntersection command interface will change so that you can select a single set and press enter twice to find the common intersection of the members of the set. In the attached file, selecting the three black boxes results in the red one. Note that if there is not a region common to all selected, the result is nothing, and you get back the input with a message saying so. If this turns out to be useful, and does what is expected in reasonable cases, I will turn it on and get rid of the test command. If you are interested, please try it out and see if it does what you expect. Boxes.3dm (35.5 KB)
