This stores the last position of all the measured feature dialog boxes.
Entry Name: MeasuredFeaturesDlg
Entry Type: String value of four values separated by commas. The first two values list the offset distances from the left and top sides of the primary monitor. They define the location of the top left corner of the dialog boxes. The second two numbers define the width and height of the dialog boxes. The dialog boxes are not re-sizable so the second two numbers don't do anything.
