+// This is the widget for editing min and max X and Y for the print head.
+// The print head is internally stored as a JSON array or array, representing a polygon of the print head.
+// The polygon array is stored in the format illustrated below:
+//      [  [ -x_min,  y_max ],
+//         [ -x_min, -y_min ],
+//         [  x_max,  y_max ],
+//         [  x_max, -y_min ],
+//       ]
+//
+// In order to modify each field, the widget is configurable via "axisName" and "axisMinOrMax", where
+//     - axisName is "x" or "y"
+//     - axisMinOrMax is "min" or "max"
