Nyall Dawson da78ddeb7c [FEATURE] New expression functions for angle/distance interpolation 
angle_at_vertex: returns average (bisector) angle to a geometry
at a specified vertex index
distance_to_vertex: returns distance along geometry to a specified
vertex index
line_interpolate_angle: calculates the angle parallel to a geometry
at the specified distance along the geometry
