+            GetManhattanDistancePointLine is an Integer function used to get a distance from a point measured along axes at right angles. Also called "taxicab geometry". In taxicab geometry, the distance  between two points is the sum of the absolute differences of their Cartesian coordinates.

+          <p>
+            In other words, Geometric distance measures the hypotenuse for a right triangle. Manhattan distance is the cumulative length of the adjacent and opposite sides for that right triangle.
