//v1.2 - 10 December 2016
//- split columns out into auto and unit options, rather than config options
//v1.1 - 9 Dec 2016
//- updated to work with multicol appropriately (thanks tbone!)
//v1.0 - 27 Nov 2016
//- initial release based on tbone's ModifiedWithin column script (http://resource.dopus.com/viewtopic.php?f=35&t=23192)
