Added new command ptGridSurfaceDomainVariable. The command divides surface domain with variable distances using surface curvature, attractor points, sun vector and random distribution. Check the manual for details.
Added new option to support variable distances. Option name is "DistanceMethod" and commands that now support it are ptExtrudeEdges, ptOffsetEdges, ptFinEdges, ptOffsetPoints and ptOffsetBorder. Distance can now be variable between a minimum and maximum values using surface domain with variable distances using surface curvature, attractor points, sun vector and random number generator.
