For a given point within a given mesh, the existing `meshWave` method gives the orthogonal distance to a patch. In meshes with very steep terrain (e.g. a hill of 90 [deg], this might be problematic for the fields that require the distance to the patch associated with the terrain surface. `directionalMeshWave` is a variant of `meshWave` distance-to-patch method, which ignores the component in the specified direction. Can be used e.g. to calculate the distance in the z-direction only. TUT: add example of directionalMeshWave to mesh/moveDynamicMesh/SnakeCanyon Requirement by CENER Implementation by Mattijs Janssens
