AlgorithmsIsConnected Method

The set is connected if the set of points are neighbor-connected, and isNeighborsConnected return true for each two neighbors in the set.Two points are connected if they are neighbors, or one point has a neighbor that is neighbor-connected with the other point.

The set is connected if the set of points are neighbor-connected, and isNeighborsConnected return true for each two neighbors in the set.Two points are connected if they are neighbors, or one point has a neighbor that is neighbor-connected with the other point. Another way to put this is, this function returns true if there is a set that connects point1 to point2.
