ENH: add directionalMeshWave functionality
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.
