add the method for write channel vertices information

- CHG : change the postProcess method in TripleCells class
revise for neglect parameter

- CHG : neglect parameter used in Pytaurus
change on the tunnel solver

-CHG : in the method for calculation supply function for current density in Substrate solver, the EffTunnelTo is not treated as empty energy level
-FIX : an tiny but important revision on method for PrintValue for string
-FIX : fix a position of typedef statement
revise the method to write Vfb shift for each slice for 2D Pytaurus

-NEW : add method to write the flatband voltage shift of each slice for 2D Pytaurus
-ENH : enhance the method for calculating the effective interface charge for 2D Pytaurus
in triple-cell structure, the trap occupation only takes effect with the vertices of the main cell
