TorqueVAWT:

--------------------------------------------------------------------------
   Torque produced by a VAWT wind turbine rotor. 
   Uses Analytical Lift and Drag Models
--------------------------------------------------------------------------
   Form:
    [t, pWind] = TorqueVAWT( w, d )
--------------------------------------------------------------------------
