[abap2xlsx] Column width Row height

Dear abap2xlsx developers

Can someone tell me what the units are for column width and row height or how to set the default units ?

  lo_row_dimension = lo_worksheet->get_row_dimension( ip_row = 8 ).

  lo_row_dimension->set_row_height( ip_row_height = 20 ).

  lo_column_dimension = lo_worksheet->get_column_dimension( ip_column = 'A' ).

  lo_column_dimension->set_width( ip_width = 1 ).

It would be great to document this in the code of the SET and GET methods of these two items.

Thanks for all the great work!
