Classifies pedestrian wind comfort per point from an annual hourly wind-speed series (the Wind Speed output of the Velocity Amplification Factors (VAF) component) against a comfort criterion (Lawson, Davenport, NEN8100). Returns the comfort category, class letter, and activity description for each point.
