This widget is an extension to the existing Columns widgets that come with the OutSystemsUI.
These widgets, specifically the "Columns Medium Left"/"Columns Medium Right"/"Columns Small Left"/"Columns Small Right" do not allow the developer to define the relative widths of the two columns given.
With the Adjustable Columns widget it is possible to change the relative widths of 2 columns using an input parameter. The widget also has the standard inputs available to these other column widgets which have the same function (GutterSize, TabletBehaviour, PhoneBehaviour, ExtendedClass).
No functional changes from a usage perspective. Moved from CSS styles to JavaScript based solution, so makes it easier to understand/implement changes.
