Input	Polygons	Shapes (input)	`POLYGONS`	-	-
Output	Statistics (*)	Shapes (optional output)	`RESULT`	-	-
Options	Method	Choice	`METHOD`	-	Available Choices: [0] standard [1] shape wise, supports overlapping polygons Default: 0
	Field Naming	Choice	`NAMING`	-	Available Choices: [0] grid number [1] grid name Default: 1
	Number of Cells	Boolean	`COUNT`	-	Default: 1
	Minimum	Boolean	`MIN`	-	Default: 1
