-the gradient projection is no longer done by taking the minimum angle between gradient vector and its projection. The local gradient at the cell scale is used to determine which face is to consider.
Some tests are removed to speed up the method.
Use the head wave traveltimes when the gradient projection points outside the tested edges.
