Various routines relating fault parameters, slip and motion across faults

fault_to_corners	Compute 4 fault corner coordinates from origin, dimensions and orientation.
geo_to_strike	Return strike for a fault segment from start and end coordinates.
rake_from_euler	Predict rake for a fault from Euler pole, position and fault strike/dip.
rake_from_slip_az	Predict rake from horizontal slip direction and motion style.
slip_rake_2_ds_ss	Convert slip magnitude and rake to dip-slip and strike-slip components.
ss_ns_2_ve_vn	Convert strike-slip and normal-slip components to east/north velocity.
strike_dip_rake_to_dir	Return azimuth of horizontal motion for given (strike, dip, rake).
unit_normal	Return unit vector normal to the fault plane in ENU (Up positive upward).
unit_slip	Return unit slip vector in ENU convention (Up positive).
v_to_n_ss	Decompose horizontal velocity into normal and strike-slip components.
v_to_rake	Compute expected rake from relative horizontal velocity and fault geometry.
