Flip PolylineZ

Running programmatically

Changes the directions of the polylines from a PolylineZ dataset. In the resulting feature class the polylines will be oriented Up Slope (start from the node with the lower Z value and finis at the node with higher Z value) or Down Slope (start from the node with the higher Z value and finis at the node with lower Z value)
