MeasurePolygonAreaOperator

class Communicator.Operator.MeasurePolygonAreaOperator(): This operator allows you to create a polygon and measure its area. Click to add points to the polygon. A cursor will show where the point will be placed. The operator will perform vertex snapping by default. Holding down the alt key will disable this feature. To complete a measurement, double click when placing a point. When there is no active measurement being created, click on a text box to drag and reposition it relative to its anchor point. If a measurement is currently being created, pressing the Escape key will discard it, otherwise the last created measurement will be discarded.
